Thats the thing that puzzeled me. I did not hot lap it. The first run I let it sit about 1hr after that about 30min apart. My 86gt is fine if I let it sit about 30min. Even if I hot lap my 86gt I dont loose that much speed. I let the mach sit a hr because it was still day light out. Then when the sun set thats when I let it sit for 30min. Dont know??? Im going to have to learn more about the mod. engine's. It is a little diffrent than my 5.0
