Did your tuner turn off the VATS theft system?

Any DTCs? That sounds exactly like what I had when I didn't have VATS turned off.

Yes, computers can go bad. Usually all it takes is a good shock, or exposure (read: submersion) to alot of water. Sometimes they just crap out.

What does your tuner mean by "not sticking"? I'm sure if the tune wasn't saving, the software would let him know that it couldn't be flashed.

Yeah, I wondered about this statement too. It either flashed or it didn't. Make sure your tuner knows what he's doing. Either way, you definitely want the sticky software
