If the cam is at 107 that should be good, timing around 32-34, under hard accelleration I see 11.0 A/F.

My timing is there. AF ratio is 11.5 @ wide open. thru most of the rpm range from 4000-5800 during water testing.

What intercooler? Is that info buried in this thread somewhere?

I've been looking at FrozenBoost and plan on getting a new one, soon.

Is your transom black when you're done, under 12.0 we loose speed. Are you still trying to run on pump 93 ? what timing on top ?

I am still running on pump gas. @ cruise I can not get over 12.3 without it popping thru the intake.
Timing is 28deg @ WOT. After 3 hours of running at all speeds I have a light film of soot on the transom. I just cant lean it any more @ cruise. I even tried the NTK O2 sensor to be sure its accruate. after the last issue I am afraid to lean it under WOT much more without race fuel.
