A good tune and tire and you're knocking on the door of 11's. Add an off road x-pipe and a converter and you're knocking on the door of mid to low 11's. My best so far is an 11.3 @122 mph while I still try and tweak my suspension. Keep the stock gears or move up to 3.31's if you plan on adding the Boss Intake. But no more gear.
