I have a 2001 3.8 v6 mustang all stock except for magnaflow cat back and cold air intake i want to make it alot faster i considered getting a sct 4 bank chip 65mm throttle body and a 4.10 gear kit and a 7.5" 28 spline limited slip differential my friend told me to put a 8.8" axel on it what should i do
To go a lot faster, you'll need a supercharger. Skip the chip. Waste of money. Out back, pick up a used 99-04 GT rear end and toss a set of gears in that.
