Today I was driving everything was working fine perfect 12 psi on my non seq twins... Well I go inside get something to eat come back out get on interstate and go wot... I get a max psi of 20!? Lucky I didnt break anything... So I set my settings from 29% down to 5% and I slowly give it gas to see see what kind of boost I get and Im still way over 12 psi... Its a Greddy Profec B-spec II, It still reads perfectly same as my boost gauge and just a little different then Power FC... I dont understand what happened it was working fine then all of sudden not? Nothing got touched

 

Look for a loose hose on the boost controller line. If you capped your wg and pc actuators, make sure those caps are not leaking.

 

I just came in from looking at hoses... Definitely a problem... The side of the boost control thing that says "NO" has a hose coming out of it splitting into 2 at a "T" then those 2 hoses run to a little metal thing that both connect to but the other side of it has a nipple that was plugged into something not sure what... I looked around and cant seem to find what it was plugged into.

Edit: Just found a picture of what isnt connected.

The thing by the "NO" port arrow is not hooked up

How it came out I have no idea... Now to see how it goes back in

 

Well I got it shoved back in... Dont know if its supposed to be just pushed in... It rotates freely but It works... Oh well hope it doesnt come out again :P

 

Hope it doesn't come loose, or hope you don't blow your engine? If you do the same thing, expect the same results.

I would look into why it came apart and not run the car until I solved the problem.
