I have checked every coupling! Tighten'd them all done. Checked every vaccum hose etc. Im only pulling -15 to -16 on my boost gauge. Everyone else is saying they pull around 20 or so. I have no idea what else t check. If i rev the car up it will of course go up to 0 then when it falls back down it hits -20 then raises back up to -15 or -16 slowly after. Any help please. Its driving me nuts. Sohc Greddy Turbo btw.

 

whats your idle at and hows the condition of your head.

 

Idles it fine ....Head is fine too. Ran like a top before all this. Havent even drove ti sence the kit has been on.

 

bump

 

its most likely a small leak if its at -15 or -16. could be coming from an old worn down hose that needs to be replaced. listen closely to the motor, manly the mainfold part for a hiss. i dont think it would be very apparent, but u have to try to listen harder.

 

Its a bitch to try and listen to it. I have a damn exhaust leak louder than **** right now on my downpipie ..Ive bought like all new vaccum hose and couplings. Im just about to take it off and sale the damn thing

 

Up for any ideas ?

 

build a pressure leak detector.

 

spray carb cleaner on every connector and flange. then wipe to a lovely shine i mean listen for changes. The pressure tester is probably better since the leak could be so far from the TB

 

Thanks ...Im gonna take each charge pipie off one by one from the turbo housing to the TB and rev each one to see if air blows out ....would this work ?

 

Bump before I try to drink it away lol

 

do you get a buzzing noise when you give it gas?
