I raced my 99 lightning vs my near stock 91 5.0 5spd mods are (CAI, and full exhaust)
we raced a 15mph rool, 45 mph roll, and 2 times from a dig and each time my 91 coupe pulled 2-3 car lengths. this just doesn't seem normal to me especially considering my coupe has 240,000 miles.
now the lightning doesn't have any check engine codes or anything and it does build about 9 psi of boost. but I did notice it had autolight platinum plugs, I changed out the front four with ngk tr6 because I had a misfire code come on and I have not don't the rear four yet. I don't know if that will make a huge difference.
