I have a '93 Trans Am and it is an A4. The motor is completly stock. And the only other mod that I have is a BMR strut tower brace. My friend has a '95 Z28 with a CAI, Granetelli MAF Sensor, Powerprogramer, 3.73s, a Mac off-road Y-pipe, and a Flowmaster muffler. And his car only dynoed at 247rwhp and 285rwtq. I thought that his numbers were low, do they seem like it to anyone else? What do you guys think that my car would dyno at. I ran it once and it went 14.6 @ 95mph on bald GS-Cs. It was also my very first time to ever race.
