Yesterday I was drivin around in the Lakehood area and I had my window down. I hear a loud hissing and wonder wtf it was.. I put on the gas and I notice I lost power.. damn boost leaks. I think its comming from the left side but I haven't really checked it out cause I'd have to take off my front bumper and crud. Hopefully I just need to readjust or tighten a connector or it could be that my intake is clogged... I first started suspecting when the warning light came on and she wasn't running as well as she had been.
Atleast its not as bad as it was previously when I had no boost =P

 

The most common leak comes from the throttle body connection....Replace all of your clamps with T clamps from Napa or the like...Good luck
