Is it possible for a Tial wastegate to be leaking? During idle i could hear my dump tube shoot out air.. It sounded as if it was leaking. And during low RPMS like 2-3krpm the wastegate gets kinda loud. Is it possible that the wastegate could be leaking and if there anyway to fix this? Also. The spring is supposed to be set at set at around 7psi. But when my turbo spools up the gauge only reads 4.5 psi. I just bought this wastegate brand new and its ****** up on me already. Someone let me know.
