Last nignt i was driving around and in third gear at about 5800rpms my boost just cut out. Now my car wont make any boost at all. It is just an Ls motor with a drag turbo kit. I disconnected my MBC and tried to run it off the wastegate but still no boost. Im not sure if the wastegate is letting the boost out or what. please help.

 

Try checking all your charge piping and make sure all the seals between them are tight.

 

Yeah just checked and one of my connections was loose. Thanks skhonda.
