I downloaded the latest OFT (i was on version 2.0)release and flashed the car again and haven't had a CEL again(Knock on wood). Has anyone experienced something like this or could have it been a hiccup on the tune?

The oft only reads engine ECU codes so it means the code was generated by one of the other control units in your car ie auto trans control unit body control unit ect.
if you buy a cheap obd scanner it will read all codes and clear all codes, however diconnecting battery or reflashing will clear codes. its best to find out what the code was before clearing it .
