The 30FF and boost leak threads have been beaten to death. You need to source the leak as there are many areas it can be.
A 30FF code and check engine light will appear when you underboost for over 3 seconds consistently.

I know for fact that it ran great with the 30FF code. I ran great for about 3 days. Than it lost all power up 3 days ago.
It's when I got the 2AAF fuel pump plausibility, is when I noticed it dropped and never recovered even though I changed to different maps.
Sure, is hooking up a air compressor and plastic adapter to do a leak test, easy said than done? So far, I checked passenger side vacuum hoses. They're fine(front side 2 braided hoses going to the canister are disintegrating on the sheath....oh some CRAP quality! Will have to replace them with Mitsubishi's). Broke the vacuum canister nipple on the underside. That's how I checked vacuum leaks
