Hi guys I'm new here,I have a 5.3 sbe with a btr stage 2 tt cam 2 bg s366 turbos 160 lb holley low imp injectors. im running a ms3 pro ultimate. I cant get the car to not run rich. at idle it runs in the 10.5 to 10.9 range . I used holleys dead times and its still runs rich.I turned the fuel pressure down to 30lbs and it helped but I know thats not right.Any help would be appreciated.

Hey, did you figure anything out? My car is doing the exact same thing. Was running perfect for the last few months. All of a sudden its just running very rich. Any help would be appreciated.
Thanks,
