If you dont rev over 2500 revs the car just barely creeps forward. Hence why in the auto revving around 2000 rpm is the best.
When you let go off the brakes, you will hit boost much quicker (3500 revs) hence a better take off. At the end of the day if you have good tyres, there wont be a big burnout... however this all depends on like I said tyres and how much power you run.
My car is stock btw.
