I can hear something at 3700 RPM
 

I can hear a pssshhh kinda sound like a boost leak, only my vacuum lines are fine and it isn't an exhaust leak, I think that it might just be my secondary injectors coming on (seeing as it is at 3700 RPM ish)...should I be able to hear them coming on? (They get louder with higher RPM EG: more fuel coming out...

Time to get an air/fuel meter methinks

Secondaries come on at 3000 RPM, and i don't think you should be able to hear them.

If it sounds like a boost leek it probably is one.. Check your y-pipe that is where most people have boost leeks...

I don't think it is a boost leak....but ya never know, I can see a small nossle coming off near the back of the intercooler (not the hose connected to the intercooler, the thing that little hose is connected to) and there is an open nipple looking thing there...that could be my problem (but a boost leak doesn't bug me to much right now because my clutch is almost gone and I can't go to hard on the gas anyways (clutch stuff on order)
