boost leak
 

I have a leak somwhere, everytime i gas it i hear a hissing sound. first it started off in my boost gauge, there was a tear in the line, i taped that mess up (probably a mistake) and it stopped for a while. But a hear it through the engine compartment. Any suggestions or am screwed to a mechanic.

Boost leak
 

Most of the time its your Y pipe coupling to your cross over pipe. The rubber hose connector usually splits open. You have to take it off and inspect it. Mine looked good from the outside. But when I streched it apart there was a split in it. Also check Air bypass valve the and your CRV connections I had to replaced those also. "Don't under estimate 10psi" I replaced everything with good silicone hose and for CRV and ABV I use 1" steel braided ( for heat resistance ) So I would definitely replace your boost gauge hose.
Don't forget to use T bolts clamps.
Here is a really helpful site for troubleshooting your boost problems.
