    in over my head!

    could anyone help me figure out how to lean out my idle? I have tried ton of things but just don't know whats going on. I have a lm7 with twin 72mm turbos ls1 heads an camshaft, 95 lb injectors. 3 bar sd. looking to put around 20psi to it. this is in a drag car an when I leave the starting line it bogs for a few sec. then goes,why?

    Looks like you pegged the map sensor. Did your replace the map sensor with a 3 bar? Was the injector data provided for the injector you are using?

    yes it has a 3 bar speed density sensor in it, I just figured out how to change my vcm scanner tables an haven't been back to the track. if I can get it to idle an run some what smooth I have a dyno I can set the truck on to start building boost.
