i have a preditor programer and it seems that once i program the truck it loses the program after i turn off the truck. Do i have to reprogram the truck everytime i drive it or am i doing something wrong? Also how do i update my programmer. My truck is a 2000 7.3l f350. Thanks in advance.

The only way to get rid of the tune is to reflash the truck, it can not go back to stock on its own.
