I just installed hard IC piping and I think I have a boost leak, because the car runs like crap. The boost level does not past 0 on my boost gauge, but reached 7 on the factory gauge. Maybe I didn't hook something up correctly. I have a electronic boost control( greddy), greddy BOV. All the clamps are tight.

 

check your gaskets. i cant tell you how many times everything looksed normal, only to find that the gasket between the IC pipe and throttlebody had fallen down. also check your hoses going to your BOV, make sure ya didnt get em crossed up, and check the gasket on your bov while you're at it.
