How much should I expect from a Stage 1 F31 B48?
I have a MY 2018 B48 330i (stock 252/350). On the VBOX (w/ 1ft ro) the best i have seen is a 5.74s.
I am testing out some Stage 1 93 octane maps, which supposedly should give me around 310/480 (crank). The best I have seen on the VBOX is 5.38s. Is something holding the car back?
I was kinda expecting better numbers because a 330/500 B58 (say on the Supra) gets a flat 4.0s 0-100.
The car is effectively bone stock except for the tune.
