Yes from what you are saying I believe it is your exhaust vent hole, which purges out the extra air, from your HPR being way over pressurized. If your noid, or anything is not already damaged, (let's hope not) you ought to be okay, IF you take your Allen key and turn down your HPR. Try turning it down all the way, until it stops. Then slowly back out the reg as you shoot the gun with the eyes off, after a full turn or two, adjust velocity over the chrono.
