When is the optimal time to let go of the brake? Is it when the RPM hits 3000-3500 (which seems relatively quickly after releasing the brake) or when the boost rises (which seems to take a bit longer)?
Stock I found that I got the best times when launching when the boost gauge got right to the B in Boost. 3.7x stock on a pretty terrible road.
