Its friggin annoying. I was hitting 14psi just fine yesterday. After installing the PWM kit, I could't hit more than 11.5-12psi on both map 4 and map 1. I redid the entire charge pipe and coupler section again and torqued the hell out of them. No dice.

The wastegates are fine, the only aftermarket couplers are on the new charge pipe, and DV valve offset tubes.

I guess I need to pressure test. I have a stock FMIC, but could those connections leak? I may put together a small leak test like Sniz who pressure tested from the hot side of the intercooler. I'm just trying to think of a way to connect a coupler to the stock FMIC without damaging the disconnect. Anyone got any ideas of how to connect a pressure fitting to the stock snap-type ring connectors?

EDIT: the leak was at the intercooler, snap coupler shook loose. Goddamit.

Before reading your edit, I was thinking to check there. I experienced the same boost leak, although not during the pmw install. If you only spent 30 minutes on the problem, consider that a win.

+1... also, did you change the Diverter Valves? that will be your next leak if you didn't - may only be needed if you upgrade the FMIC

Yep, I'm using AWE diverter valves. I was actually troubeshooting for many hours before I posted, and THEN found the problem. I'll get a FMIC next season.

this probably re-assures my problem with my BMS meth kit.

I cannot boost anywhere more than 11 lbs and i believe its something to do with my intercooler.

But not having a garage to work with limits me checking there so im just waiting to purchase a new FMIC and hopefully when thats installed, fixes my problem.
