The quarter mile time is at 6000 feet elevation no low elevation! Just installed my Christmas present, got dual Flex-A-Lite electric fans. My 98 GMC 4x4 is Lowered 3" in the front and 4" in the back. I had to buy new rims because my other rims were too wide, so I purchased BOSS 311's. I also added a chrome airdam with fog lights and billet insert. It features Projector Headlights, Clear corners, Clear parking lamps and a Cowl induction hood up front. For performance it has headers with true dual exhaust toned by 40 Series Flowmaster mufflers without catalytic converters and o2 simulators, Throttle body spacer, Velocity stack, AEM intake, MSD coil,distributor,8.5mm wires and had Hypertech tunning before super-charger. Under the Hood dress up includes Chrome Valve Covers, almost every item painted red and red loom over every wire and nut covers over every nut, also has an Optima red top battery. The other exterior features are chrome trim and i just added chrome handles, chrome bed rails. I just added a ATI pro-charger a few months back, with 11 pounds of boost and it is intercooled. Also changed my 3:73 gears out to 4:11. My dad and I have done every bit of the work to my truck, Thanks dad for all the help.
