I'm having a bit of an issue, I'm running a 60MM HX40, I was running around 40 PSI on A Holset HX40 with BC272s, I then swapped out to a more aggressive GSC S2, since then the car has only been making 28 pounds of boost. I've tried increasing my boost controller, but the boost just doesn't increase anymore. I've done a boost leak test and there are no leaks, but the tester bleeds down a bit fast, I assume it's due to the Bigger cams. Any thoughts on what the issue could be?
