The truck went into limp mode last night. 07.5 Lmm crewcab 4x4 2500hd. It had the particulate filter message come on. I grabbed my ppe xcellarator and tryed to clear the codes and run the regen. It would not. I limped it home after I loaded the stock tune. Brought the truck into the dealer and they ran updates to the computer and then were able to run regens. Problem is on my ppe programmer there is a back to stock option and stock tune option. I selected the stock tune option not reading the instructions. I took the truck into the dealer with the stock tune in the pcm with tire size changed. The programmer should have used the back to stock option and I did not. Got it back from the dealer and once I got it home I tried to load my tune from the pcm. It not only dropped the tune all together from the truck, "now it wont even turn over". Also lost all my tune files in the PPE. Does anyone have any recommendations or am I screwed?

Call PPE and you need to get your tuner reflashed, they can save it but till then you wont have a truck:(

try the back to stock otion on the tuner if tht doesnt work unplug the ecm for 15 mins and reconnect. if tht dosent work you might beable to send it back to ppe or it will need to go back to the delear.

FYi look under the i bleive diagnostics option for the back to stock not under the normal tuneing screens
