Well here I am just cruising along tonight(17psi), camaro comes up wanting to roll race, so I drop it down and slaughter him, car ran like a dream that time and has NEVER had this problem at all for me. He wants a lower roll so we go back out, I drop down, boost won't go over 4psi, BOV isn't blowing off, and my car sounds like its got a mad exhaust leak, so I pull over and check all of my charge piping and the silicon boots holding the piping together for rips, everything is fine. Check all of the injector clips push them all down hard, put my hand in front of the wastegate and its blowing a decent amount of exhaust out.. Weird. Vacuum is dead even at 20psi so thats fine, I just don't know what it could be.. I was tryin to get some ideas for when I wake up in the mornin to go mess with it.. Could it be the little valve in the wastegate is stuck down, or clogged or something, or the spring may be bad or something? Any suggestions would be greatly appreciated..
