Today, as i was driving home, i noticed that my car seemed a little slow. So, i floored it and checked the boost gauge, it only read about 4lbs, it is supposed to boost 7. I continued to try to figure out the problem and i noticed that at full throttle instead of the wastegate being loud as hell, it was not even audible whatsoever, also the blow off was supressed too. The turbo spools up normally. My setup is T3/T04e, with drag IC piping, spearco IC, blitz bov, HKS Wastegate, MF2. HELP PLEASE. Thanks.

 

One of the intercooler pipes has worked itself loose more than likely. Your wastegate is not loud because it isn't opening at all because of the low boost.

Check all the intercooler piping connectors and clamps.
