I have a 93 fd with hks downpipe hks exhaust and pettite boost controller premmaped to 13p.s.i. and hks intakes. Last night i was driving regular and I started to get on the throttle and hit max boost as usuall with no problem..A few minutes later of non boost i try to boost again and from 13 p.s.i I can only achieve 6p.s.i. I hear alot of air when i try to get max boost. I have friends who tell me this my be due to a line or hose disconnected. Please help me I just cant take not having my second turbo kick in. And also I want to time my car at the track in sacramento tommorrow..thanx alot

 

You have a boost leak. Get under the hood and start troubleshooting.

Start with the couplers and go from there (you actually have to remove the couplers and inspect them).

You may have popped off a vac line, or one of the hoses in the intake system may have a leak.

Damn, Rynburg beat me to it!

 

thanx guys im reviewing the link right now..I really appreciate it.

 

Damn there is so much wires and most of the dang words or i mean abreviations i dont know what the hell they stand for.

 

Not wires you should be concerned about. You should worry about vacuum lines....
