Did a compression test today...

Compression looks fine.

I looked at yer mods list, and noticed Stock MAF & Screen ?? I'm not speaking from experience, and mostly out of my arse, but wouldn't that limit air flow to a certain cu ft/rate ???

Nick is right, I have an old ZZP HVTB Stage 2 TB which is 72mm throughout with a matching 72mm plate. It was fixed up by GBP too sometime ago.

As for the stock MAF, i've had no reason to replace it, I was never maxing it out last I checked. As for the screen, that helps the MAF read better and should be left in all MAFs IMO.

Ok okokok. My first thinking was just more spins with out more pressure makes me think of a restriction up-stream. Or a bad bypass. I think simple first. And I'll do it again.... Collapsing Intake hose or filter??
