Gotta question for you techs: Before I took my 04 X in last week I was running strategy code: VXBC9BB TQBF0N5 - flash CTR8

After they changed out the Elec. Throttle Controler I find they must have reflashed my truck as it is now Strat. code: VXBC6N2 TQBE055 Anyone know what flash # that is and why Ford did it?

Thx
