I have a weird noise now when on full boost, it only happened since i fitted the heatshield on the kstech intake, to do this i removed intake and the pipe going onto turbo, i also loosened off actuator bracket o refit my turbo blanket, now all back together and all connections seem super tight and i get this whistling noise on full boost. Boost is solid and consistent too.
so its could be either:
Leak in fmic pipework somewhere
Problem with actuator
stock bov final is busted and leaking
Answers on a post card, im hoping its just a bad join somewhere thats easy to reach and not one of the couplers on the core which would involve bumper off again!
