Prolonged squealing noise during a WOT or slightly less pull.

Hello, a while after installing my intercooler I started to hear a loud, kind of squealing noise whenever I do a pull. I am pretty damn sure it's a boost leak but unsure where it is coming from exactly. I made sure that all my hose clamps were adequately tightened and that they were fastened correctly. What's weird though is that after doing a few more pulls the noise disappears until the car is stopped for a while. Was wondering if anybody else had experienced something similar, or if anybody knew where the leak could be coming from. Thanks

Did some data logs and peak psi sits around 28-29. I am not exactly sure how much boost the stage 2 EQT tunes put out, but my guess is that it's around what I logged. So a boost leak is somewhat canceled out.

Not necessarily. If it's squealing it's a boost leak. You can see if it's post intercooler by comparing boost psi vs relative manifold pressure. Post your logs to datazap and share them. If it is pre-intercooler it will show up on high wastegate duty if it's bad enough. otherwise get a boost leak tester.
