I made 3 pulls on a dyno-jet dyno over the weekend. The car is all stock with a K&N filter. It has a little over 4,000 miles on it. I didn't plan to run the Camaro, but the other 2 projects I had in mind weren't ready. The first pull was 288.6 hp/307 lbft at the wheels. Pull 2 was 286.?? and 307.??. The third pull, I swapped the K&N for the AC the car came with. The hp was back to 288 and the torque was up to 311. The dyno operator mentioned that the engine was a bit leaner as well, indicating better flow with the AC. I've had the K&N on it for about 2,500 miles, it's clean and not over oiled. Does this surprise anyone?

the best test for MAF being miscalibrated is to turn it off and just run Speed Density (IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif)
