If you will read just a few of the replies about the Sprint Booster (just do a shearch on sprint booster) you will find 99 out of 100 love it and will say it is the best mod they have done. Keep this in mind "it CORRECTS THROTTLE LAG ONLY, IT DOES NOT INCREASE HP!" and it works. Another thing it does not just move the TPS to an early WOT, WOT has nothing to do with it. Buy one, you will like it.
