You can’t beat the power delivery of the OTS tunes from bootmod3. Fresh trim looking sweet excited to finally see this 😍

[@TimWilliamsHD]

You know it bro! Likewise, needs the defined coding sauce!

[@goflex3052]

Always good vibes with my man Tim

[@TimWilliamsHD]

Thanks bro, loads more to come!

I’m a big fan of BM3, I have it on my B58 Z4 M40i.
Sports cat, replaced the opf with a resonator, mst intake plus multimaps makes it a lively beast.
Unfortunately I have Michelin Pilot Super Sport which are hideous in the uk winter so I’ve gone back to stock power temporarily.
A great feature I like is boost by gear adjustment.
I’ve got 40% torque reduction in 1st gear, 30% in 2nd, 20% in 3rd and 10% in 4th.
I’ve not done it yet but in the absence of valet mode I might use map slot one with maximum torque reductions in every gear.

[@TimWilliamsHD]

Ah you know man, works so well!!

[@craigd9840]

RUclips and its algorithm is brutal! how have i not seen your videos before? looks like you create good content. subbed

[@TimWilliamsHD]

Thanks dude! Much appreciate it! Hopefully I can get my name out there more this year!

[@craigd9840]

@@TimWilliamsHD yeah man you should, your videos look well thought-out and edited well. i watch 90% of the car youtubers for years and not seen yours! crazy how you can be hidden.

[@Bman4717732]

Wow that sounds amazing

[@TimWilliamsHD]

Cheers dude it’s a beast!

[@charanlachhar1585]

Fresh car, fresh trim !!

[@TimWilliamsHD]

Haha trying bro 😎

[@connormurray7536]

Hi Tim, do you have bm3 flex fuel installed. looking to flash the bm3 multi map but i dont have the flex fuel atm

[@williamsphysicseducation237]

With bootmod 3, you need to do torque reduction by gear. 1st gear 30% 2nd gear 20% 3rd gear maybe 5-10%. Hooks up much better.

[@TimWilliamsHD]

Will give it a shot when I can!

[@williamsphysicseducation237]

@Tim Williams it's located at the bottom of the menu when you are making all your selections. By the way... Great 2nd name 😆. 👏

[@TimWilliamsHD]

Haha thanks dude

[@bimmerflex5526]

Let’s pray you get to keep your license!! Your M4 needs the German autobahn’s!

[@TimWilliamsHD]

😆 always obey the speed limits

[@williamsperformanceltd998]

We need to test out the race fuel map 😂

[@TimWilliamsHD]

Jesus I’m gonna have to block you 😆 such a bad (good) influence 😂

Is bootmod3 hard to use?

[@TimWilliamsHD]

As easy as the video mate

[@AGM240i]

Go on dyno to see the numbers.

[@TimWilliamsHD]

Potentially! Would rather wait till stage 2 hardware fitted then text them all
