Is it married???

Hello fellows I need to know something important.I have a U7193X and used it on my 2004 Sierra 5.3.Excellant product. Now I sold the truck and have this programmer and want to sell it to someone who has an '06 gm truck.Is this predator going to work on his truck or is it married to my '04?What if anything do I have to do as it's no good to me anymore?

if you put the stock tune back inthe first truck, it is unlocked, if not, it is married.

The U7193 will not work for an 06, just 03-05 models.

Thanks

Yes the '04 was of course returned to original when I sold it.Thank you for your answer,so I can sell it no problem to someone with an '03-'05,great.
