I have had the GIAC on the car for about two months now. The other day the car stoped making full boost (1.2 hKpa) and is now making about .6 hKpa if im lucky. So i thought it was a boost leak and had the car presure tested at a local shop (good shop) They said there was no boost leak. However they looked into the ECU and found a code (something to do with the emissions vacume line, said it was a small leak). Also they reset the boost ranges, so it ahould be right back up to the 1.2 hKpa range. I took the car for a test drive and there was no change, the car was still makeing about .6 hKpa.
My tech who put the GIAC on the car said the car woud go into a safe mode if it saw something michanicaly wrong (sensor, turbo, etc...) However I had the shop pull codes again and nothing came up.

I have the baily motorsports DV on the car and they are less then 1 year old. so i dont think they are the problim.

THis is frustrating the hell out of me if anyone knows what might be up pleas help

Also this leads me to think it is something that does not have a sensor on it (DV, Turbo, etc...)
