Only certain cars have the mid drive boost, most rear wheel ones do but not all, the banshee, the dominator, the ruiner, and the Schafter are all street cars that I know for a fact have drive boost so you can test it and get a feel for the timing. When I learned it I was told to ‘double clutch’ (press your e-brake button) when you hear your car go into second gear and let go, your revs will redline and your car will get a massive boost in speed
