I have an 07 ms3 with a turboXS FMIC, CPE SRI, Cobb turbo inlet, and a Greddy BOV with the ATP turbo/street unit adapter flange. I had an issue the first time around (before the FMIC & turbo inlet got installed), and the first flange I had didn't seal properly. It was thin, and it took a bit of effort until I eventually got a perfect seal without any boost leaks. This is all while I was still running a TMIC and no turbo inlet btw.
I could tell I had a leak at that time because of the sound, and the loss of power. I used locktite, I think it's called, because I stripped the threads on the flange and it eventually fixed the problem completely. The sound went back to what I would consider normal and the power was back. I had it dyno'd and it made wonderful power.
Then I installed a TurboXS FMIC, and had an issue with the flange. I ordered a new flange, and ATP is making their new flanges twice as thick with a rubber gasket on both sides. Good. It needed some improving. I also installed the Cobb turbo inlet. I know there was a leak at first, but if there's a leak now, its not severe.
However, it still feels like my car isn't making the power it should. Without taking it back to the dyno, how can I tell if I might still have a boost leak at the BOV seal? The sound is deceiving, because I don't know if it's the FMIC piping combined with the new turbo inlet I'm hearing, or if it's a lingering boost leak at the flange. The turboXS intercooler and piping is larger than necessary, so it's possible I'm experiencing the power loss from that. How can I tell if I still have a boost leak? I have a boost gauge, and as far as I can tell, it holds boost at around 12-14ish psi. As a last resort, I probably will be taking it back to the dyno. I want to anyway. Ever since the first boost leak, I swear I'm paranoid. How can I figure this out?
Help!
