Hey I have a boost problem. She will not boost past 5-6psi and does not want to pull under full throttle. What could be wrong with her? She cranks and drives normal..just wont boost. I changed my spark plugs and vacuum lines.

All my mods are in my sig. below.

Any help/suggestions are very much appreciated.

 

btw i checked the intercooler couplers as well already.

 

Sounds like the secondary isn't coming online.

No I'm running a single turbo setup...just recently tuned by Kan.

 

pressure tested?

 

meaning compression test??

Car cranks, idles, and drives fine...no loss in power or anything just no boost when its suppose to boost.

 

no,intercooler test for pressure loss.....at least its what Jim @ JPR did for me

 

I would pressure test also.

 

no pressure loss...still running like crap...anymore help/suggestions??

 

is the car running good other then the boost issue?
can u sustain the 5-6psi until redline?
