I recent installed a new turbo inlet, bypass valve, charge pipe and a post maf hose kit from my air box to the new inlet. I have triple checked all connections and even added new t bolt clamps. However I still have a boost leak that sounds like a vacuum. You only hear the vacuum noise at 17 psi boost and on. I am wondering if I now need a new 3 port boost controller, new intake and tuner??? Maybe it’s making too much boost for the stock boost controller to handle?
What makes this problem better or worse?
It’s worse when you get into boost
