I need my PCM flashed to a factory tune. My predator will not let me backup the stock file because it says its a performance tune. This is a crock of crap, because I just had a buddy of mine pull the tune out with an SCT, and compared it to a stock tune, and it was in fact a stock tune. So the only thing I can conclude is the checksum in the tune is different. The VIN in the tune matches my truck as well.
