Vacuum leak or something else?

This just happened this morning, yesterday the car boosted fine up to 15psi.

Started car, noticed my boost gauge read -20 instead of -15 like it normally does(i have a street port). Once i was about halfway to work and the engine was warm i wanted to see if it would boost right and punched it in 2nd, only got to 4PSI with WOT. AFR gauge says i was running rich the whole time too.

soon as i get off work i am going to check all the hoses. i am running non sequential stock twins...heres to hoping its just a little vacuum leak ^_^ lol

no ideas since i am running non sequential i guess?

So what was the problem?

Bad Gauge or loose fitting?

loose coupler. didnt have time to check it before i posted due to clocking in as soon as i got to work but i just went out there to check it while i was at lunch. waste of a thread :D
