Can't store original back... Says may have program

[Justin95L]

2000 model 7.3l I try to store factory back up it stops and says it may have program installed. Truck does not drive like it has program, my dads 02 7.3l stock feels the same before his predator was installed and have driven many stock and chipped 7.3 trucks checked for chip in port on ecm none has hvk4 ecm

Perhaps there is an old tune on the PCM from an other flash tuner?
You may want to consider having the truck reflashed at a Ford dealer to be sure it has a stock tune on the PCM.

Thanks

I went to ford and had them update the pcm watched them do the update and it still says the same thing.
Should I try my dad programmer install his factory tune back in his truck and try his tuner on my truck?

Nah, give us a call here, and we'll try something over the phone.

Thanks
