i have an 06 with a bully dog triple dog that is doing the exact same thing. the rough running is intermittent, seems like it does it more often when it gets hot. same two codes 2146 and 2149. if yall find a solution please pm me

 

05 has normal valve cover gskt, injector harness goes thru three connectors in rocker box. these are electrical codes highly unlikely to be caused by transfer pump or lack of fuel

 

Edge harness is probably faulty. Plug the stock connectors back in, clear the codes and see if they return. You can still clear them w/ the Attitude, as long as it's plugged into the OBDII connector.
