Boost Controller Problem

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

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.
