So i am getting an ls swapped vehicle going.
2010 5.3 6l80e, tsp 220r cam dod delete, magnason supercharger.
i have the vehicle running, but it seems like the trans is in a limp mode, stuck in 3rd or 4th gear.
i am getting some communication codes and not sure where to go with it.
is this a tuning issue? is there something i missed?
codes are.
u0100-00 lost communication with ecm
u0121-00 lost communication with abs control unit
u0140-00 lost communication with bcm
Thanks for any help.
