In this video, we review the upgrade "Stages" for cars that come with the B58 engine and expected power output.
"Stage 1" = Stock
"Stage 2" = Downpipe
"Stage 2+" or "Stage 2.5" = Downpipe + HPFP
"Stage 3" = Turbo Upgrade (Hyrbid or full turbo Kit)
In general, there's no need to upgrade your intake, charge pipe, or spark plugs.

This guys a different breed, I watch these videos even tho I have a n54
Thanks so much for the support
Fantastic info man
Just joined the b58 engine club(coming from an r35 GTR)...got a stage 2 tune with a catless downpipe in a x3 m40i..and boy, it gained 100 hp..doing about 3.7 sec to 60mph..loving it!! BTW, got the x3 m40i for the same reason I got the GTR, best value for your buck!
Got a 22 m40i and looking to go stage 2 in future. Is yours a 21? And what tune you go with?
@@SL0Z07 flash is MHD..the tune is custom by the tuner
@@SL0Z07 just went full e85 and added a high pressure fuel pump..doing 0-60 in 3.5 now
@@SL0Z07 it's a 2019
Hearing this stuff gets me excited 😁 I'm about to tune my X3 m40i as well. I can already tell the B58 in it is superior to the N55 in my M2!
Bro, you give the best info, and to the point. I dig the channel. Keep it going. BTW what is your wheel set up?

@Raul Aguilar it definitely can be. get a good tune and proper fueling and enjoy the car.
Will be buying my 4th BMW soon, God Willing. I have been Looking for something like this FOREVER !!!!!!!!!!! Your information flow matching the logical evolution of this engine is the absolute BEST
I have ever heard and believe me I have 2 Doctorates in You Tube. Thanks soo much for this !!!!
I am loving the b58 in my 440. Such a beautiful driving experience!
good for you, man! One day I'll join the club
@@jotabarberaIV Yes in due time you will! Prosperity!
same. i just got my 440i m sport coupe yesterday! im in love.
@@howdyimdan Welcome to the club my friend 😎 Just yesterday a M4 Driver pulled up to me and said he loved how the exhaust sounds! (I always drive in manual sport mode +)
I have a b58 , Xdrive 440i. I have BMS air intake , CTS turbo catless down pipe , Stage 1 tune on 91 octane. I got 330 WHP and 430 WT
got my 2021 supra last year and im so glad u made your channel for the info
Keep it coming bud🚀
This is pure gold Kevin! Thank you sir 🙏🏻
Best Video!
Personally I run Stage0+ (Soon Stage1) already got 300cell DP. I just can recommend the DP and xHP even for stock cars. It makes it much more responsive and shifting not only in Sport/Sport+ nicer but WAAAAY smoother in Comfort. Just get xHP.. Also reminder, you have to go ~60miles in comfort, no kickdown, no manual shifting, no sport mode after flashing xhp to let the transmission get new gear adoption values etc.
Can you explain stage0+. Is it like a custom map that is not as boosty as stage 1 maps?
@@baronmunchausen645 The engine comes from BMW in a lot of different models. In each model it has a different kind of power/software. Stage0+ is basically the highest setting that BMW provided for a model and you can use this values on your engine to.
It basically is stock, but not stock, if that makes sense
Yeah it's the MPPSK tune for F30.
Right now I'm running a decend 440 hp stage 2 with about 635 NM of torque and it suits perfect for a M240i. Everything above is like just burning Tires for no reason unless you really wanna compete in Dragraces. Guys be safe out there and choose a good tire if you want to have performance for your HPs.
hi, can you tell what upg you got for 440
Fck, these engines really sound like they're bulletproof for some minor mods. Never thought I'd see a turbo BMW be able to handle 500whp on stock internals. Crazy.
Very clear and informative video, well done matey.
Been running just a remapped standard car for a year, 411bhp/576nm, and going for a 200c ell sports cat next month, hopefully 460-470bhp and 630nm.
I had a gain from 424 hp/590 Nm to 460hp/650Nm after stage 2 ( Wagner catted downpipe)
@@jarasw8226 Nice result Jaras, thanks for sharing.
My m240i made 421bhp and 471lb ft on MHD stage 2 with 100 cell cat, not sure 460-470 bhp is realistic unless you have 102 Ron/oct
@@b16dans I think 450+ is about right for a sports cat.
Mine was dyno'd on a very conservative dyno, and made 336bhp stock on 99ron V power. After a custom remap, it made 411bhp/576nm on the same day.
That was stock everything. The performance specialist I take my car to said 450 is a realistic number for a 200 cell sports cat and further remap, with 600 to 650 nm.
I have seen a few make 470-480 with a sports cat, but I think those figures are exaggerated by either roller riding, ambient temp lies in the calculations, etc.
420 REAL bhp is about the maximum for a stock car with a custom remap. So I think the map on yours is not very good mate to be honest, I'd get it to a trusted tuner for a custom map, several dyno runs with the map tweaked each time for maximum power staying within safe temp/timing/fuel limits.
@@DjNikGnashers I guess it also comes down to the dyno and the guy operating it but I was told by the tuner he has never seen 400whp from b58 stage 2 on his dyno. And my figures were slightly better than a bm3 stage 2 b58 he had in the day before
Thanks for being you and sharing your experience and knowledge.
my m240i pushes a bit over 600hp on 98 with a Hybried Turbo a Dorch Stage 2 HPPF and a Catet Downpipe and im now going on E20-E30 and look what the Car is going to make
Great Information brother, give thanks 🙏! I just bought a 2019 540i , thinking about stage one for starter
I just saw your TikTok on my fyp and now your on my recommended videos 😂
Haha sometimes the algorithm works in my favor
Great video! Going to go stage 1 on my m140i soon knowing that the engine is capable of much higher
Just did mine on Friday and damnnn that engine is sleeping in stock tune! Got my eyes on a sport cat and maybe a cat back.
Solid info, thanks for making this
Great video brotha
Great video! Thank you for your contribution!
Great video broski! 🤘😎
The video is really useful. B58 stage 2+ also gives 450-480hp power. So how much power would the S58 give at different stages?
Getting a Stage 1 Tuning next week. It will be 430hp 580nm
Loved this video. so much knowledge THANK YOU
Thanks for posting 👍
Excellent guide. No need for some knob driving around saying check out my MHD generic settings. 👍🏽
Amazing vid once again! 👍
Thank you for this vid 🙌🏾🙌🏾
Got my m240i with the b58 2 weeks ago with only 50k miles on it and just loaded it with stage 1 with intakes and DP along with xHP stage 1 and WOW, it literally feels like my chest is being pushed through the seat when you put your foot down at 40 mph
Would go stage 2 but wanna ease into the power haha, next month I'll load the stage 2 file with a exhaust system then once the performance is done because stage 2 will be more then enough for me, I'll do interior and exterior mods! :)
cool, enjoy it
Mr. Kern, Very informative video, I wanted to ask, at the end you posted some values, the gains in terms of HP depending on the stage, however, the cards for other videos linked are blocking the last two i think, anywhere else, i can go and see those?
Dude where was this like 4 months ago?! good stuff man!
Boss I’m having a crazy issue I deleted the pcv with the port from the heads and car still smoking bad and after I do a pull oil is leaking oil cap, my car is stage 2+ on 93 I replaced the gasket valve cover oem one Injectors sparks
Still got 3 years and unlimited miles on my M40i’s warranty. After June of 2026, I may start modding.
Is there any benefits to doing an XHP trans tune with just a stage 2 tune? Is it worth the better shifts, or just a waste of money?
I have a b58 , Xdrive 440i. I have BMS air intake , CTS turbo catless down pipe , Stage 1 tune on 91 octane. I got 330 WHP and 430 WT
I’m new to a boosted car and bmw. i just got a 2016 340i and I’ve been watching most of your videos. Is there a specific reason why we don’t need spark plugs? Your helping me learn so much about these cars btw 💪🏾!
I guess it just depends on mileage.
Dumb question- but are most ppl that are running careless DPs bypassing CELs with just an O2 sensor spacer? Only thing holding me back from the downpipe is the dreaded CEL..
Do you have a video on maintenance schedule for tuned cars?
What are your thoughts on going with colder plugs. I’ve got an x7 planning on doing a Catted DP with a MHD stage 2 tune.
Can I get those tune from a bootmod3?...and can I upgrade down pipe...fuel pump if mt car is 2022...and I don't wanna flash computer yet..."warranty"
Keep up the work. Love your content coming from a 440i coupe owner

Perfect video!!!
I have a BMW x4 M and I got a Downpipe and ecu tune and e25 and i got like 250 extra hp the mods are worth the cash
Great way to save the intake manifold is to get an oil breather cap. Massively reduces the pressure
that's not how that works.
@@kern417 Reduces crank pressure which reduces pressure across the entire engine
@@saucysimpson259 the intake manifold is not connected to the crankcase
@@kern417 I know it's not but it reduces the pressure across the entire engine
Just picked up an Ineos Grenadier w/ B58. I am thinking the stage 1 is an easy upgrade? True?
I have a 2018 740i and can’t find much info on modding, do you recommend or think it can be done just the same ?
Hi Sir, Can you guide me how to replace the heat management module?
I took it to our local BMW dealer and they said that it's check engine light because of heat management module is bad
Hey, I also have a manual but I have some questions. At what kind of power did you decide you needed to upgrade the clutch and did you do the flywheel as well? I feel like 2-2+ would already be in the range of causing slipping sooner rather than later but maybe that wasn't the case for you?
Hey, do you recommend upgrade draft shafts once big turbo? Will be doing diggs with the car
You should do one on What are stock Drive train limits like axle ,and Diff, driveshaft etc
I’m assuming these stages are different than a JB4 stage tune. Is it worth upgrading to an MHD over a JB4 if you have a catless down pipe/intake/charge pipes?
hell yes bro mhd will do ur car wonders if you already have supporting mods
Do I need an upgraded fuel pump either 2019 440i? Cuz I know its a gen 2 pls let me know
New subb. I love the vid, thank you for all the info. Was considering changing out my charge pipe and down pipe on my 340 6speed before going stage 1. Was told the B58 charge pipes are stronger than previous gens so don’t really need to do it. Didn’t really plan on going past stage 1 but if i’m already swapping out down pipe and that’s the only mod necessary to go to stage 2 i mite as well. My question is, if i just swap my down pipe for a high flow catted one and go stage 2 i shouldn’t run into any problems rite? Also, what platform would you recommend? Been looking at MHD, and Bootmod3.
There's no need to replace the charge pipe. I have a video discussing that as well if you check my channel.
No issues with stage 2. Both Mhd and Bm3 are good Tuning software. Personally i like the interface of BM3 but you can download both apps to see which you prefer.
@@kern417 appreciate the prompt response. About to go check out the video now. Thank you.
Solid video. Really glad i came across.
I have a 2019 540i xdrive
BMS intake
VRSF catless downpipe
VRSF charge pipe
JB4 tuner and i usually sit on map 2 or map 3.
What “stage” am i? Have not done dyno yet
Equivalent to stage 2 from the major tuners
I bought a used 540i with 60,000 miles and I’m contemplating just doing stage 1 . Ideally I’d like to drive this car a bit past 100k miles and I’m sure it can do it just fine.
Its fine, as long as you do the maintenance on the car.
great break down. i know audi / vw stages like the back of my hand but now that i want to switch to the bimmer life this was invaluable for the b58
So the charge pipes are solid in the b58? i remember that being a big problem in the n55
Yes
@@kern417 do the charge pipes increase turbo sound and add any hp even 5? I know the intakes add about 3-5 and more sound depending on the brand.
Those power figures you post at end is that for rwd or awd applications. Big difference. If a stage 1 rwd is 380-400whp the awd version is at least 20hp less
No it's not
What’s up guys,
I have plans for over 500hp. Although, I’m at a toss up. Should I upgrade turbo first then install meth kit? Or meth kit first then turbo?
Great video
Do you have any experience with Hybrids ? I have a bmw G05 45e. Just got down pipes installed 300 cell, and looking at ECU tune and custom exhaust with GPF delete. Tuner states around 500-520hp for stage 1. Should be no issues with engine and transmission. Any comments here from your side ?
I heard it’s recommended to run ngk 1 step cold plugs is that true?
Is the stage 1 safe for stock clutch and gearbox, for manual transmission?
@kern417 im currently running a catless DP, intake, visconti flex fuel kit on a 30 and 50 map getting 540hp 570tq on high map. Could i squeeze some more power with a hpfp?
what about with b48 do you think this would still be the path to go down?
What do you think about the M Performance Power and Sound kit?
From bmw?
One question and a suggestion... can you run full E with a stage 2 LPFP upgrade (is that the only Upgrade needed)? the suggestion... would be awesome if at the end of the video when you flash up the tunes and the power output if you could add another column to provide approximate ET and mile per hour for each of the power levels. Some people chase Dyno numbers (which is silly as it's just a tuning tool and they vary) others chase performance numbers, so would be good to know for stage 1 OTS the typical car will run 12.2-12.5 @ 114-117 for example. appreciate your chanell!
@kern417 Darnit! Just found out your in Cincy! I was there the other day getting a carbahn tune at jake Sweeney bmw… so far I have AWE exhaust with AA downpipe.
I got impatient and did the tune with 10 months of factory warranty left, but I also added the Carbahn matching warranty.
It’s not a huge bump, but enough to notice! In your opinion this should be a fairly safe and mild tune??
The plan is to switch to Ecutek or BM3 next year once warranty is done. Awesome content btw!
Yeah it's safe
At one point is it required to have a TCU tune? Im planning on going MHD Stage 2 HPFP, xHP tune is in the plans, wondering if its safe for the transmision to be running those power levels on a stock TCU tune, thanks!
Hey man! Thanks for all the videos and forum discussions! Loving it. I have made my g30 b58 gen1 up until this point to stage2+, but now stuggling a bit with settings for MHD tune - particularly should I tick the box for TCU TQ limiter removal or not? In theory mhd says st2+ is up to 520hp and 720nm, so even in a worst case scenario i would imagine my engine will be exceeding 550nm limit of the torque (apparently stock is around 450nm so with st2+ should easily go beyond 550nm, shouldn’t it?). Thanks for help in advance and again, loving my car now and your videos helped a lot!
do you have xhp?
I have 2019 440i xdrive. Got it at 30k miles now it’s at 60k miles on mhd stage 2. About 25,000 miles on stage 2 no problems. How many miles will it stay reliable? Daily use.
As long as you keep maintaining it.. lmao. Warm the car up, turn turn it off straight after some pulls etc.
On point with everything,very nice video,congrats. On an M340 with pure 800, downpipe, change pipe,hpfp, and a Trans tune , on 93, it is possible to run more than 600whp? And it’s a daily what should i upgrade more?
There are no hpfp upgrades for an M340. There is also no need for a charge pipe.
On 93 i wouldn't expect more than 550 but some people have pushed it further.
Currently running a custom stage 2 tune, 455 hp and 618 Nm on my M140 Xdrive. Recently had the TU pump fitted as precaution. Is it worth re-tuning to stage 2+? Will the power gains be noticable from stage 2 to 2+ ?
With the TU pump it wont be that much but it would still be an upgrade over stage 2
I love you
Hi, Do I need a KN or BMC for stage 2? Or OEM is enough. THX
With the exception of geography in the engine bay. I would like to assume that most of this stuff can be done to my g05 x5 40i. Is that a correct assumption?
I have driven a modified 40i of a visitor to Toronto that hung out with us for a week. I could really feel it just tooling around Bloor St. I dont know what the mods were except he had a box inline for one thing. Other than that, you couldnt see anything. I would really like to do something to give it some oooomph once that thing is all mine in October.
Depending on the year it will be more difficult to tune
Hello! What about the Air Intake? You have yours replaced, as we can see.
Hey looking to get a TU PUMP and help with where you buy one online would appreciated
MHD also requires a GPF delete for stage 2 but I never see anyone do it. Any thoughts?
I had a quick question regarding my manual 2018 340i. I got stage 2 E30 from BM3 running right now. I had an issue where I would go WOT and around 4k rpm or so the car would make loud pops and cut back on power. It wasn’t consistent. Sometimes it would happen and sometimes it didn’t. The RPM it would happen at would vary at times too but usually around 4k. At first I thought it was my clutch was slipping. So I had it replaced because it needed to be replaced anyways but that didn’t solve the issue. You got an idea of what that may be? I’m hoping it’s just me not having a good e30 mixture.
most likely, but you need to run a log to confirm.

Hi! Can i put a better intake with the m performance kit? Does it work ? Or I have to change the exhaust system or downpipe? I Mean can i make stage 2 with the m performance exhaust?
What about downpipe on bm3 stage 1? Worried about putting the stage 2 with manual clutch. .🤔🤔🤔 Keep going with this b58 videos.
The manual clutch will hold stage 2 pretty well. Going above stage 2 e30 is when it tends to slip
i have bigboost turbo stage 4 kit on my x3m40i and I got 550 hp ,it can go up to 700 hp with port injection
When did ur clutch start slipping
Still loving the content on this channel and please keep it up! I just installed MHD today on my 18' 340i RWD. I fitted the FTP chargepipe and intake pipe with a drop in BMC filter, catless downpipe and the TU pump. I went with 91 Oct stage 2 and did a dyno run. The results were a bit underwhelming 269wkw (361whp) and 587nm of torque. Do you think this is normal and could be a stingy dyno? Also the tuner that helped install my hardware said he does not recommend even loaded the stage 2+ even though I have the pump because in South Africa our fuel quality is poor. Would love to hear any thoughts on this.
How do the logs look? On 91 octane that's not bad.
@@kern417 it looks fine according to the tuner. There are some timing corrections. Boost is at 1.28.
Yeah probably just limited by octane. Just enjoy it 👍🏾
Would you recommend Stage 3 Custom Big Turbo Kit for time attack track use on BMW 840i RWD ? Or Stage 2+ should suffice in terms of power efficiency (no wheel spin) ? Please advice, good people 😸
From what I have experienced when you want them suitable for track better is less hp cuz of less wheelspin and easier control of the gaspedal. But if you build it custom with everything needed suspenion tires and other stuff then 600hp is also okay but you will have problems with traction that is why I would stay with a stage 2 or stag 2+.
In the video, when you're talking about up-grading internals and cracking intake manifolds are you referring to BHP or WHP??
Whp
@@kern417 Thanks
hi, great info thanks, i have m240i manual with mhd stage 1 tune and a de cat downpipe , dont like the smell now so want to put std downpipe back in, does that affect the tune as stage one is generally ok with stock everything ?
Should be fine
thinking about getting a 540i and then taking it to 550hp and 800 nm how much would i have to spend?
Hey Kevin. If I want to add an aftermarket CAI on stage 1/2 for better noise not performance. Would that be detrimental or great compared to the OEM intake?
Most quality intakes have no difference
@@kern417 Thanks for the help, much appreciated!
hey boss!! I have a 2020 m240i x drives completely stock thats about to come off warranty. Keep it as is and trade it in or enjoy it for a year or two with a tune? thx
That's up to you man
why did my b58 started losing oil, smelling a lot like it from the exhaust and and smoking white clouds when accelerating? i did the Stage 2+ just as how you described it, 60k miles on the clock atm
Could be anything. You'll have to dig into it to see whats going on
Check your PCV....
Thank you
Did you have to use an E92 M3 clutch MC conversion with a CDV delete to make your DocRace kit work?
No
I have a B58, 2018, 540i BMW and I’m looking for recommendation who does the best tunes? and a tune that’s compatible for down pipes as well because there’s a lot of people that do tunes, but don’t tune for downpipe’s
ruclips.net/video/Ugkn4OHwqk0/видео.html
Hey man I recently did a downpipe and stage 2 bm3. Got codes for clutch slipping “badly” and intake VANOS. I can’t pull hard at all without dropping revs and going wonky. What would suggest? Just warranty the clutch and do the vanos and hope it works ? Manual transmission
I’m also thinking about deleting the cdv for more “clamping” force
Try swapping the actuator from intake to exhaust side and see if the code changes. If so then replace the bad actuator. For clutch slip yes I'd replace it but i doubt you'd get it under warranty
I have a 2018 440i with MPPSK is stage 1 ots tune any upgrade over my bmw upgraded tune? I heard number sit around 360 with the bmw tune
If you have 93 or e30 yes. If you only have 91 then not much improvement but there is some
pops and bangs from the downpipe are great
Is the 550i clutch hold the torque from the stock turbo on stage 2+ and the GC+ on pump only ? Probably around 550whp or less
