545 rfe trans easier?

From what I have read here, there is a reflash needed if you want the security turned off in the ECM. I didn't state that in my reply, and it may have been confusing. According to what I have read here on FABO, in the New Hemi Swaps section that we're in right now....you have to get the ECM reflashed to cut the security feature off UNLESS you are using the ignition switch and chipped key from the vehicle your ECM came from. If this isn't correct, I guess i'm being a parrot in passing on a few other peoples bad info.
