Charlie,

Can't remember the slip % but 22 mph loss.

5 lbs. fuel flow

at peak power total timing is set at 34.8, initial is about 14.

Piston lands look good, tops of pistons had detonation marks. All the rings spin free, no friction. I went back on my dyno sheet and the A/F ratio was 12.3 and not 12.7 as I said earlier.

I thought I had a 12* module in the retard box but it was a 10*. I will put a 16* module next time and work from there.
Basically The shift light stayed mostly on the entire 1/8 mile run. (set at 6800) I just kept shifting it. It used to come on right before I cross the stripe on a 1/4 mi run.
