Recently, whenever I hit boost a weird squeaky sound comes out and im not sure where its coming from or what is causing it. Initial thoughts are some kind of leak in piping due to the fact the gauge reads the boost when max to be less than what its supposed to (used to get to 6.5ish now only 3.5ish (×100mmHg))
Help would be appreciated. Link of video is on this forum post wasnt able to do so here

Blown a gasket maybe?
Happened to me a few years ago, was manifold to turbo gasket that was shot, sounded terrible!

I used the opportunity of removing the turbo's to replace them, if only I hadn't already unknowingly had steelies fitted beforehand 🤣

Yeah, boost leak test. Go get some PVC caps and some tire valves. Pressure with an air line and watch boost gauge so you don't go crazy psi and listen for leaks. Soapy water will bubble and reveal leaks.
