I've got a 2012 GU713 Mack w/ the MP7 in it. The engine ECM gave out, and we replaced it with another from a garbage truck off an MP7. But, it doesn't have a Jake Brake on it or the same HP the original did. Looking for someone to flash it for me. May be able to get original flash file from old ECU if needed to. Who do y'all recommend on here that's pretty trustworthy?
