I traded in my 2000 Silverado 5.3L so I can't use the hypertech any more. Yes, I did return the vehicle to stock before I traded it in... so the programmer will work on another vehicle now.
The programmer is:
Hypertech Power Programmer III for 2000 GM Truck 5.3L
(I think it will work on '99 models also, but I won't guarantee it...)
It comes in original box with instruction manual, cable, and even the Hypertech stickers!
Bought it for about $340. Used it for almost 3 years and enjoyed the noticable performance boost. I'll take $220 for it... PM or email me... Offers considered...
