I went 83mm, 10:1, cuz i knew i’d be doing my own tuning and all that

u can just go 9:1 and have that extra margin or whatever, theres no real big diff between 1 pt of compression when ur boosting a B.

i meant 83mm in that post anyway, must’ve been a typo.

Slip looks ok, u prolly wont cut any better than a 1.9-2.0 on BFG’s…u need a set of real slicks, warm em up good, dump it at 8k, cut a 1.7 , and run your high 11 @ 120 (turn up that boost to 15psi son)
