C5 loses to 80-90, then walks away

[Rev]

That'll be simple Sky. All I'll need to do is bump the initial 4 degrees to 18 and that'll make 40 total all in by 3000 RPM. I will have to check for detonation though on the plugs. Me being half deaf and the Flows kind of drown out anything I might hear when I'm really on it.

I did review all my time slips. The usual trap speed was really only 98-99. The 100.3 was a one time only deal, but did occur. The old average was about 14.0/ 98.5-99. So I really got an improvement of .3/2.5 with the new heads. I hope the extra timing will help. Again, thanks for the advice.
