I ran my car at Mason Dixon Dragway yesterday and averaged between a 15.4-15.5 and I did hit a 15.3 once. Not bad considering all I have is a cai, shifter, and msd wires. Next time I go I plan on having some better tires, an exhaust, and I want to let the engine cool down completely for at least one run to see if that helps any. Hopefully within the next few days the Northern Virginia Mustang Club will have pictures of the drag day up on their site, there were some sweet Mustangs out there! I think the best time was a 8.9
