Part of the problem is lag from the from the Precision 6466 turbocharger. This is something automatic 335's will have to figure out how to mitigate.
Specs for the 2008 E90 335 on this run are full interior, full weight, over 1/2 tank fuel, and a e85/93 mix. This is on the stock motor, stock automatic transmission, and around 30 psi of boost. This car was built by Proven Power in Florida and tuned by Jake Hershorin of proTuning Freaks.
There is room to improve here significantly but the problem of course is the automatic transmission which can not be launched hard and is slipping at this roughly 700 wheel horsepower power level.
Congratulations to BimmerBoost member @Ak335i, Proven Power, and proTuning Freaks.
