From a roll, stock Golf R would pull on a stock 328i, stage 1 + DP 328i would pull on a stock Golf R, and a tuned Golf R would pull on a stage 1 + DP 328i (with our current software options at least).
Basically, tune a Golf R and our 328i's have no chance with current mod options
Making these assumptions based on the pulls I made with a Stage1 + Intake MK6 GTI and comparing various dynos of this setup Vs Golf R setups.
