Well said, there is NO answer to this question. You have to find out for yourself.

 

I asked my parts de[t about tuners, if they sold the xcalibrator. He said they had a super chips reflash or some such but not the xcalibrator. I then asked if there are warrenty problems with using a reflash type tuner, which he responded no, they cannot tell if it is flashed or not if you put it back to factory before bringing it in.

I take that with a grain of salt since I doubt the parts dept guy is a certified mechanic but probably true, I'm sure he talks with alot of the mechanics and works with people buying their ford racing stuff.

 

All the dealers have the same info all under the VIN number. Anything that has been done to you car is on world record. Switching dealers will not work. You will be in deep --it if you don't flash it back whenever even getting close to a dealer.
