I'm selling the O.E. Super Chips programmer that came with my Radix kit for a 1500 series GM truck. Model years compatible: 03-05 (not 100% sure).
The kit was ordered for my 05' VHO Silverado with the LQ9 6.0L.
I don't think the programming is any different for the 5.3 trucks, but I could be wrong.
It is new in the box, never used.
Asking $225 OBO. PM me.

Thanks,

Jim
