So over the weekend I got going on installing my hdi gt2 intercooler and hpfp internals..
After everything was done I took the car for a spin, although noticed a problem.
When I was hitting boost there was this strange whistle sound coming from the engine, I looked over all the clamps and there was no sign of any leaks.. and I've currently blocked off the BOV port. Although when hitting boost I was keeping boost, so didn't feel like I was dropping any psi and my cobb showed that it was holding boost ?
This sound only happened after I installed the fmic
