    Default Twin Turbo 4.8 wont come off idle

    I have a twin 60mm turbo setup on a 2001 silverado 4.8l running mafless 2 bar cos3. 42lb injectors. It has a loping idle and when the throttle is tipped the engine dies. Anyone have any ideas?01 boost master.ctz. The only way to get it off idle is to set the B3647 table extremely rich.
