Isuzu NPS 4x4 - Why you should tune your truck
HTML-код
- Опубликовано: 7 авг 2023
- How anybody lives with the performance of the 4HK1 Isuzu trucks (NPS, NPR etc..) is beyond us. A simple tune transforms the way the trucks drive.
Watch us demonstrate the difference in towing performance with our development NPS.

Wow, what a huge difference, also great colour for the truck, don’t think you could’ve gone any more orange than that 😅
It's different haha
TRUE SHOW WHAT CAN DO
Massive difference! What a dog it was stock hey, crazy it can tow twice as much as what the Evo and trailer weighs with stock power.
Yeah! I don't know how anyone does it!
I certainly understand your reasoning for doing this, but what are the implications with regard to Isuzu's inbuilt torque limiting feature when in low range, will it still keep the torque limited to the factory specification in first and reverse gears?
We can retain it or bypass it.
@@staytuned9176 Thanks.
Big difference! What psi boost is she running tuned?
We run 23 psi of boost on these with a stock exhaust
Hey bud I’m keen to do this as we will be towing a 4T caravan. You reckon it’s worth it for towing? We’re getting a trans cooler put on as well. I understand it voids the warranty but just checking if it’s worth it. Also what speeds you reckon I’ll be doing with a caravan with out the map ?
Hey mate, definitely worth it. They are painful standard. Even our race setup here (would be lucky to be 2.5t) would see us down to 60kmh on lots of hills. Send us a message on our Facebook pages and we can organise to get you slotted in somewhere, you will be over the moon. facebook.com/staytuned14.7
Some one asked the question of price which you didn't answer, can you clarify that ???? also what year is your NPS I noticed there is no Lane departure crap on top of the dash, I have just taken delivery of a brand new 45/155 NPR and it has the same amount of left down steering angle on it, did you not ask for that to be rectified at first service or is it considered to be an Isuzu anomaly.
We won't respond to pricing enquiries on RUclips. Send our Facebook pages a message / give us a call and we can clarify that for you. Our steering is off in this video due to suspension changes, nothing to do with Isuzu. We have wheel aligned it since. The 4x4 models don't receive the lane departure tech like the 2wd models.
Hey guys! I'm in the states and have a 2007 "Sterling" model thats a rebranded Fe84D apparently. Is this something that could be done on this rig? I use it for a tree service truck.
Hey mate! Not familiar with that particular platform. Send us an email and I can take a proper look for you. Info@staytuned.net.au
I have 95 npr is it possible to tune that? Im in the states. Thanx so much!
Hello Michael, unfortunately it is pre common rail and would need the pump tuned manually
Can this be done over the internet around the world?
Yes. We work with lots of tuners around the world to deliver tunes remotely. Where are you based?
That's all good and well... do you tell the customer to keep the revs at 1800rpm up a big long incline??
The radiator can't handle the heat if you try getting to the top as fast as possible it boils. My experience just cruse up at 1800rpm "no rush"
Your delusional. The cooling system will handle it perfectly fine. 1800rpm at 90% throttle is worse for exhaust temperatures than 2400rpm at 50% throttle. Don't give anyone that advice....
@staytuned9176 so your telling me you can go up Toowoomba range at 2400rpm pulling 3.5t behind your tuned nps 300 at 100%
And no extra heat...
@palma8120 that's not what I said at all. Of coarse if you are at 100% load for an extended period of time the heat energy has to go somewhere. The cooling system on these is extremely robust and I have yet to be able to put it under load long enough to exceed 102 degrees centigrade (and that's on the dyno or big hills).
Who did the tyre fit and suspension upgrade? cheers
@@MORT-zf3qb we do the King suspension and associated components in house at Stay Tuned
I have one on order , my only concern would be giving izuzu another reason for refusing warranty on something
It's always something you need to weigh up. The chances of the tune causing a failure is extremely low. Remember, the modification has to be proven to cause the fault. Also, a shop like us will stand behind our product if it did indeed cause an issue
@staytuned9176 do you have more info on your tune ? And cost ? Cheers
@justinworden7051 absolutely. Send us a message on our Facebook pages and we can run through it all! facebook.com/staytuned14.7
So the obvious question has to asked, is the modification legal?
All factory emissions equipment stays in tact, so yes.
A microphone would have been an idea.
I turned it off at 3 mins in…. Couldn’t hear a word from one of you.
Hi Ken, yes we are aware the audio was suboptimal. We have rectified this for future videos. We encourage you to watch the rest of the video, anything inside the truck is perfectly audible.
Excellent video on tuning!
Altering the factory tune will void your warranty and if your paying 100k
For a new truck I would suggest it’s not worth it, as soon as you alter or modify anything warranty is void.
That's not true at all. If the modification is proven to have caused a failure, that component will not be covered. If you put aftermarket wing mirrors on your truck, and the gearbox explodes, it will still be covered under warranty. These are also that abysmal standard, most people would prefer to take the tiny risk
@@staytuned9176 mirrors and tuning a engine is completely different and not what I was talking about haha
@Dan_128 it was just an example. Obviously it's not for everyone however they are such a poor driving experience standard that most people don't mind the small calculated risk
@@staytuned9176 Isuzu specifys in their warranty agreement that if you alter or modify anything in the truck without authority form Isuzu their is no warranty
Working an engine harder than it was originally designed for is not a good idea
The harder you work and engine
The shorter the life span
I wouldn’t take the risk on a brand new truck
I agree
They are very slow from factory
Painfully slow to be fair
I would take the risk on a older truck
Just not a new one under warranty
@Dan_128 that's not legal just FYI. Each to their own.
Tune ..
Ironic,,,
Audio & Microphone....need tuning
Or we just need a microphone? Thanks for your feedback
