boost troubles
I just got my boost gauge installed today. I went to do a boost check and while i was wot stoped i recived no boost. moving I recive no boost until 4500 and then i get 5psi from there to red line. I have checked all the tubing looking for leaks but found none. Has anyone else had this problem what does it sound like it is to you guys. A leak somewere i hope.

well, you dont get any boost while ur stopped and i think you get 6 pounds stock boost anyway. maybe the installation might me bad or ur losing a pound of boost somewhere.

yeah should go 10-8-10 stock as mentioned....your gonna have to check some vacuum lines and check for boost leaks. vacuum looks a little low for stock ports but that could be nothin...try searchin the forum too, before ya get jumped on.

do you hear a "woosh" sound under boost? if so it sounds like a coupler between the turbo to the crossover to the intercooler to the intake elbow.
if you don't hear a wooshing type sound that sound slike air escaping then it is vacuum related which is a pain.
list any aftermarket parts on your car, mileage etc. oh and check the newbie stickers for some good info about booost issues and such. no searching involved just click and scroll through the various topics.

i was driving when i checked the boost. I dont here a woosh sound under the hood. It looks as though there are brand new couplers installed. i just got the car about 3 weeks ago. i didnt have a boost gauge at the time but the car had alot more power when i bought it. It had a complete compression test at kd rotary in tx. along with all fluids changed and complete check up. They said it had very high compression witch they inreturn belived the car had a rebuilt engine under 12,000 miles. It has no upgrades at the time i have a downpipe and a intake in the mail. Thanks for the help
