Anyone else experienced a boost leak after installing PWM?

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.
