Looks like the seller thinks those would be for the 5.3 Alpha, but Hypertech doesn't like that application, and that isn't the part number for the I-5's. Those are older units.

Hey chucko99 did you ever get the programmer installed and if so how much of an improvement did you see performance and mpg wise. And by the way is your hummer a 3.7L?
