F/S: hypertech programmer III for 02 tahoe

Handheld programmer for a 2002 Chevy/ GMC 4.3/4.8/5.3/6.0/8.1/ vortec engines. It's worked great for my tahoe, i honestly noticed a difference. I'm selling cause i'm going to get a custom tune and no longer need the hypertech.
Works great if you have over size tires so you can adjust for them. Also harder shift points. Can play with your shift points, rev limiter, top end speed......
looking to get $180. PM me if interested. Thanks!
