I am pretty sure most of you are like me, we want to have a 400WHP NA M3 but just can't hit it. M3's stock power can range anywhere from 330WHP - 360WHP on the same dyno! So this got me thinking, is it how we drive and take care of the car? And can we potentially damage/decrease the power of the car with money shifts, bouncing off redline, accidental redline with cold engine, or abused by dealer like me (revved the car to redline with cold engine:
