Need more detail!!!!

Did you buy the SCT new or used? Which model SCT? Is this the first time you used the SCT? Did you save your stock file on to your PC?

GAWD I hope he saved the stock file first!

Shouldn't the unit save stock prior to tuning? I had the xCal2 and it did..

When you try to start the truck, does it crank? Do you get anything at all? I had this issue with my old 6.0 and I ended up having to replace the PCM.

Yes the unit should of saved his stock file, but sometimes poop happens and the unit screws up and looses the stock file. This is why it's important to always save a copy of your stock file to your PC. SCT support can send you a recovery file that will allow you to load the stock file off your PC to the SCT device, then return your truck back to stock.
