It seems, since this change my car got slower. I was running more in the 15.3's before the computor change. I had the cold air kit and true dual exhaust done along with the wires before the re-tune. maybe I need to go somewhere else, except that Lamatta has been in major magazines for mustang performance. I did re-check my dyno-page and it does show going from 11.2 to 13.5.
