2000 5.3, 2 bar OS, Comp Cam 54-000-11 .605/.610 cam, twin 70mms, when we go to start it with all sensors in place it will fire up the die. If we disconnect the O2's and IAT it will run but very rich (wideband not installed yet). The tune attached is parts copied from another file downloaded to try and help as all we have tried gives the exact same result. Please help and thank you.
