I have someone interested in a DSP5 tune and he's wanting to give me cash. This guy isn't a close friend so if his computer goes tits up I'll be in trouble. What should I do before hand to tell/see if the computer will crash? Should I make a stock file into the DSP5 upgrade that has the same operating system number as his truck?

Ended up pulling a bunch of fuses, having to do a security relearn, and finally a stock file off tunefiledepot to get it running again.
