I found THE guy in middle tn. for all your module programming needs! Mike at WellTek, 1052 4th ave. south, Nashville . 615-736-5604.
He swapped my ecm with one from a junkyard, flashed it programmed it and learned everything including keys. All for $200. He even had to get online with gm's foreign car factory site.
Super knowledgable and friendly.
I recommend him for anything.
He doesn't tune. Just factory stuff.
Yeaaaaa! I finally have my car back!
