Hey guys I was just letting you know the dyno numbers that I got last weekend.
I have a 2010 GT Premium Auto and it put down 269 hp/ 272 ft lbs torque. I have a Magnaflow Magnapacks and Steeda underdrive pulleys. I was really hoping it was more but the guys at the shop said that the drive train loss is 18-20 % with an Auto. But that puts me at around 328-336 hp and 331-340 tq. at the crank.
