It wasnt flashed at the dealership.....the diesel mechanic is a good friend of mine an he did it at my house.....so there isn't any invoice.....

Hi there I figured I would post on here beings I can't get through to tech support on the phone. I had my truck at the dealership the other day and they ended up reflashig my computer with my 100 hp tune in it. The tune is now gone and I don't believe I can recover it. So my question is what do I do ...
