Re: hypertech code
Did you restore the other truck back to stock first? The tuner is VIN locked so it can only be used on one truck at a time.
I had a Hypertech tuner get fubar'd on me, my batteries were low and the cycle was cut off halfway through. Luckily, the truck worked stock but the tuner wouldn't let do anything until I had it reflashed by Hypertech. It was part of the warranty and didn't cost me a dime. Not sure what code came up but it was a letter and number like yours. Give them a call if you can't get it to work, they seemed to be pretty good people to deal with.
