Thanks for your help. I guess "several mods" sounds like the truck is wild. I just really have the basics CAI, Dual Exhaust and TB spacer. Most of the other stuff is body trim, lift kit and radio.
Would you think it is worth spending the money to have the dealership flash it back to stock or just get a programmer and start tuning?
