I have a 2004 Oxford White Cobra with Kooks LT's, Kooks X-pipe, JTL RAI, borla mufflers with Flowmaster piping, 2.76 BF pulley and 100mm idler, and a Pro 5.0 shifter. I took the car down to Scott at InTune Motorsports in Charleston, Tn and had him tune the car. He has a "heart breaker" dyno (Mustang Dyno) and the car put down 430 rwhp and 452 rwtq :banana:. Scott was very impressed with the numbers, because he said most of the other 2.76 pulley cobras on his dyno usually put down 410-420rwhp. The car is a world of difference from when it was stock pulley and I have had a grin :lol: on my face since I went and picked up the car Wednesday.
