Check my signature, all my mods are there. The sprint booster (to me a waste of $) just make the car believe your pushing the pedal further than you are. Its like taking half (my words) the distance of the pedal for full pedal travel. In my opinion, it does nothing except make the pedal travel much shorter. I consider it if you press the pedal 1 inch its like pressing it 2-3 inches (press it 2 inches its like 4-5 inches response). That's all in a nutshell.
