I have I/h/e, msd sci, centerforce clutch, and the cam, springs and retainers, and cam sprocket. The weather THAT time at the track was very cool and it was dark, thus the track was almost cold eliminating all posibilities to launch at anything higher than like a grand. I dont know about loosing alot of low end torque, the motor has only around a hundred to start, All i did was run the fuel tank to empty and put about 2 gal. of 100 octane....smells nice:rofl: Anyway i would like to head back to the track on a much warmer day. The very first time i went to the track on a hot day i just had the msd and exhaust and ran a 15.9 at 82, so i know for sure it can be dropped well below that. Im not to familiar with the OBD2 setup, so im not sure exactly the power gains there.
