Hi i have a 02 L and i live in oklahoma. I have a diablo stage 2 chip, boost bypass, ehxaust, c&l intake pipe with mass air flow sensor and cold air intake. My best run is a 13.9@99, my 60ft. time is a 2.01 and my 1.8 mile time is [email protected]. Shouldnt my truck be running faster. I am goin to take my chip because it runs the exact same time with it on or off and put on a 6# lower pulley with a 60 degree themo stat, and the diablo predator. I am hoping that this will drop me into the 12's. My friends 03 L has a k&n air filter, 4#lower pulley and a diablo chip and he ran a 13.1@104. Also if i put 20's on my L will it slow it down any.
