I am selling my HPtuners with EIO cable. It will work on any 2002 V8 Sierra, Silverado, and/or Avalanche. I am gonna go for a fully custom dyno tune and will no longer need the tuning software. This is version 1.7, the newest version. The EIO cable is brand new, only had it for a month ($150 upgrade)

I'll take $500 shipped. email me if interested [email protected]
