I just did a turbo install. This was my first time tackling such a project. They are just steel wheel upgraded oem units. On idle it runs completely fine, as it always did. However, I took it out to bed the brakes and noticed that it won’t boost. It idles at about -6 vacuum on the oem gauge and will only reach as high as -.5 at full power. I have triple checked for leaks, no pipes or hoses blown off or not clamped. The actuator arms are not loose or blocked in anyway. The turbo blades are not locked and are spinning, but I don’t hear any spool while driving. I just put on new ex-manifold, exit pipes, down pipe, high flow cat, and full exhaust so I don’t think anything is clogged there. Any ideas or help for me? The engine is not in protect mode as I can freely rev it. The only oddity I notice is if parked and I rev it will drop a few hundred rpm below typical idle for a few seconds when I let off. I’m completely out of ideas or fixes for this thing. Any help would be much appreciated.
