Range programmer for chevys SOLD

Range technologies obd2 programmer. I had this in my 07 avalanche to keep it in v8 mode. Some of the Chevy motors are know to produce issues due to the cylinder deactivation and some people just don’t like the lag it creates when switching back from 4 cylinder. Anyhow, this thing plugs in and keeps the vehicle in v8 mode without changing the stock tune. Works very well. I’d like to get $120 for it. Works on a wide range of Chevy vehicles. Look it up on amazon for more info. 302-379-7796.
