I run my angel air at 450 psi output, so the mini reg is basically functioning as nothing more than a gas through foregrip, and my consistency is through the roof. How's this at the chrono? I set it at 450 psi, and every time I go out to play I get 287, 287, 287, 287, 287, 287, 287. And that's on an old AIR unit (the new ones are supposed to be able to supply lower pressure at a more consistent rate), so there's no harm at all in gutting the mini and just using your adjustable reg, as long as it's a good consistent reg (i.e., AIR, DynaFlow, Max Flow)
