You picked up .4 in the 1/4? From n/a to boosted@10psi.. Something's not right have you monitored loss in Trans/converter?

Yea there are a lot of differences that make it impossible to compare apples to apples.

We'll look at the timing etc soon. Info were a betting man as it sits there isn't much left. But more boost coming on quicker, and meth to help us add more timing will be a game changer. I still bet you will need a couple hundred RPM more to get the 60' you want... But not much, and the thing will be a monster on the back half of the track. I see 120 trap speeds in your future no problem.

Screenshot of a log would be nice to see from 0-60 or so.

That's cool ask them if they could port the stator while in there.. If it were mine I'd like to see 35-3800 when brake stalling. Porting stator would help that. Loosening it up I wouldn't go crazy on it if you like the way it stalls.. Not sure how much customizing they can do..
