[gatorrb76]

bought tuner from a freind that was selling his truck and he programmed it for me was having some power issues with the truck and decided to return it to stock tune but would show programming then come up with a error software version is 2.00 and hard ware version is 1.00 lucky me the truck still starts and runs and it is stuck on the 120 hp tune

Id recommend sending that older tool in for the hardware up[grade and have the truck flashed back to stock at a dealer, then start over with the new tool.
