I've got the newer USB version of HPtuners for sale. It's got the credits for 01-02 GM Trucks (will tune all 01-02 GM Trucks, not VIN specific). Its the EIO model with the hookups for the wideband.

It will also scan just about any late model GM vehicle.

$500 including shipping to 48 states.

email me at david_a_waters@yahoo.com

I'd prefer paypal.
