My turbo busa as long as your crusing around has no problems. The minute any boost hit it puts codes C24 C25 C26 C27 any ideas and could this be the power commander? It has pc111r on it. Or coulld it be a the map?
that code is for something in the ignition system specifcally ingnition coil, ingnition wiring but could also be the pc. i would check all your connections to the pc make sure everything is tight then try to find a different pc an try that. i doubt its the map. . jc
