Did a boost leak...
Had 3 leaks.
1. One was the vacuum line to the bov, easy fix so I fixed that.
2. Second leak was the throttle body seals. I ordered the WORKS last week, and had them put in today. The leak was fixed.
Good quality 
3. Boost gauge line was leaking where it was 'T'd off at the intake manifold. I tried zip tieing everything, and it still didnt fix it. So I disconnected the entire line & hooked it back up like stock. Checked for leaks again & now im hearing a hiss around the top left portion of the intake manifold. Its not very loud at only 15psi and I cant see to find ANY line thats visible on top thats leaking. I moved my fingers over the back of the intake manifold & cant seem to feel them either.
Im not sure where to locate it, or is there some sort of plug in this general area that is known to be leaking?)That might be similar to the throttle body seal issue) LMK what you guys think.

there are a few vacuum lines under the intake manifold that could come loose.
pressurize the charge pipes again, this time wet your hand with a spray bottle and feel around for the air rushing out. I had a leak on the bottom of the manifold that eluded me for a couple weeks till I figured out this little trick.

LEAKS FIXED!
I kept hearing the hissing around the top of the intake manifold. After searching over & over and never finding this leak, I began reaching behind the intake manifold, tugging at some lines, moving lines side to side to try and hear a difference in tone. BAM...sure enough i heard a difference in tone. It was a group of 3 vacuum lines T'd together. I ran my finger down & felt an actual HOLE in the vacuum line. Pulled it out, and it was a pretty damn big hole. The metal nipple had rubbed a whole through the vacuum line. Quick run to Autozone fixed it. Pressured tested and ZERO leaks!
