Low boost after FMIC install

M3 Eater · 04-17-2011, 09:47 AM

I have been going round and round with high boost applications leaking boost. Since installing a cheap fmic with no bead on the ic tube, I went on a witch hunt for the issue. In my travels I replaced the fmic altogether. In doing so I believe I pulled on the inlet charge manifold trying to get the coupler off and loosened it, at least from the front side turbo. I found the front side turbo v band loose and tightened it back up but I am wondering if there is a gasket, the the DP gasket for the same type fitting, that I may have damaged when pulling on the manifold tubing.

Does anyone know if there is a gasket there and if so, what its called, part #, diagram etc? I have been to the oem web site and they don't seem to isolate that part.

Besides less power what other things did you notice about how the car drove? I had some work done on the car and when I got it back it has less power and when Ipress the gas down hard the caroscillates/surges like i was pressing and lifting off the acceleartor repeatedly. Trying to see what possibly could cause that
