On this forum, I've heard guys warn about taking your KR in to Ford, that a mechanic may reflash your PCM. I've also heard some say not to worry about that because the mechanics know not to do that to a KR. Well!! While taking my KR into Ford to have them look at my clutch for a possible TSB replacement, they decided that the clutch was alright and it didn't meet the criteria for a TSB replacement. "BUT, we reflashed your PCM!!! YIKES!!! I nearly passed out. In the end, the manager of service at this SVT dealership said that she could not get the KR tune. That they would have to take the PCM out and send it to FRPP. I called FRPP and after paying $150, they sent me the tune for my KR. I slid the flash card into the ProCal II tuner and my original KR tune is back in. On a side note, these tunes from FRPP are not Vin specific, they are year specific.
Rule #1 If you take the KR in cover and put a big sign on the PCM port. Do Not Re-Flash!! This is a KR...
Rule #2 If you have a TVS installed, you most likely have a TVS FRPP tune or an aftermarket tune. Return your car to stock before taking it in. Then you won't have to send your tuner back in to have it unlocked. That is typically a $150 charge, but if Ford reflashes your PCM, SCT will unlock the tuner for $75.
Rule #3 - Don't forget rule #1
