Good to see a behind the scenes video! After changing the AFR and boost accordingly, do fault codes' triggers still function accordingly but to new parameters? E.g. fault code will register if the car is running too lean compared to Michael's intended AFR?

2:18 I thought it was a gun box 😂

Are you all able to tune G20 M340i? Heard the new B58 has DME locked - need to do bench unlock.

Hi brilliant video do you guys have any outsourced companies in the UK..thanks

where can I get that rear diffusor?

So what was the Dyno BHP?

It's safe to read on bench compared to obd2 on bmw

great mod for nice car but that spoiler is overdone .. IMHO

pleasr do let me the know the owners name or the spoiler...cause that sick in my opinion & i want it!

Did you guys dyno it?

Are you Able to tune 2021 models

What exahust is this? Does it work for the G21 320I?

Stock,the meter dashboard show 260kph only,your mods meter show 300kph-330kph?

Why no Dyno? The uprated numbers are 350 HP? How much torque generated sir?

No dyno run?

Wow here my goal

Where are you located ?

the way he coded m3 cs 😭

Why the mast ?

WHP???

it didn't have turbo whistle sounds??

This will surely void the warranty right?

What front bumper and lip is that? Looks sick

M3 cs with a 330i badge 😂😂😂😂

what is the max horsepower you can tune this g20 and how much?

So.... how much would you sell 25% of your business for? You guys are so professional.

The turbo lag on these cars....yawnnnnn.

This guy doesnt answer any comments😂

Singlish? 🙈

Just drive your cars in stock :) or expensive repairs are waiting for you. Then people complain that BMW is not reliable and junk :)

Actually i think this car comes with around 300 NM torque from factory. But u guys mentioned 400NM stock 🤔🤔

These cars pull a lot of timing. Mine has been tuned by various tuners, supposedly to 300whp+, but the car really doesn't feel like 300whp car. The RWD model can't put down the power, and these engines (B46) is generally very lazy, especially, at lower RPM. My 0-60 time is 5.3 seconds, which is similar to stock. IN contrast, my Audi A4 B9 Quattro (similar curb weight) was tuned to a verified 285whp and it was a monster (Dragy 4.6 s, 0-60 time). Likely because it had Quattro AND a Dual-Clutch. That car had a surge of power at any speed. Also, it can be driven hard, in 90+F temperature all day, without significant heat soak and pulling timing.

In the video@ 8:20, your 0-100kmh (0-60) run took, at least 6.2 seconds, which is worse than stock..... so on the road, I doubt you are laying down anything close to 300whp. The cooling on the G20 330i sucks. At least the F30 had an intercooler, which was upgradable. Heat soak is certainly a factor.
