i maxxed out my ip today and plugged my wastegate. i still only got about 600 degrees on my gauge (about 900 at the port then). could my pump be worn and not delivering as much fuel? i do get some black smoke when i floor it now, but everyone talks about those egts like reaching 1200 is common but i cant get near it when i try to. i dont know what the symptoms of a worn out pump are
