BMW M3 & M4 ECU Remapping: These cars are so much fun to tune. They’ve been around for years, with each new generation topping its predecessor. We took the F30 M3 to the next level with our Stage 1 ECU remap. This resulted in a whopping 520BHP and 730Nm torque! With those figures, your fast M-car becomes a monster.
If you aren’t sure whether to get your own M3 or M4 remapped with us, give us a call or send us an email and we can discuss how to take your car to the next level.
There are a number of tuners who offer similar products however it's the customer service and personal service that sets JF apart from the rest (as well as an amazing product of course) It's the 2nd car I've had tuned and wouldn't go anywhere else, I will always recommend them to friends and forum users. Thanks again John!!!
