only 7 psi still ??? :(((

[romanoodles1]

I have an 02 wrx with a manual boost controller and have noticed recently im only getting 7 psi no matter how much gas i give it...I was thinking it is either my mbc has died or my boost solenoid died because 7 psi is wastegate pressure i believe? Is there anyway to check to see if these are the problems? Any help would be awesome

Could be boost leak. Check all your IC hoses with soapy water.

any other mods? how were you measuring your boost & in what gear?

Wastegate pressure. Your MBC got done broke.

I have been having the same issue i have narrowed it down. but some of the steps i have tried.

1. check for vacuum leak.
2. check to see if the pill is still in the hose connected to the wastegate.

Your running both an MBC and the stock BCS?

[romanoodles1]

Yes the car has a turboxs mbc and a stock boost controller solenoid....where is the pill located? It used to boost fine so i dont see how this "pill" could of just fallen out?

You are running wastegate pressure. You need to get a tune on your can and throw away (or sell) the MBC, unless you truly have the need, modications for it

I found the stock boost controller was the problem in my car. I bought a new one and bam good to go.
Of course this was after checking the vacuum lines.
