On an lly, need to tune for twins stock/75. Wondeting what all needs to be changed? I know mass air flow sensor, but how about desired maf table? And are you guys lowering max boost from the valley charger? Or just making normal boost with it?

And for rescaling the maf, is (π x R2) pie x radius squared method sufficient?
