I sold my Chevy Duramax and pulled the tuner before selling it. It is ready to tune a new truck.
Here is some info about it.

I only have what is pictured (the box and some of the instructions are long gone).
It is obviously used (I believe I purchased it in 2011 and it rode around in the glove box of my Duramax until last week.
I am asking $200 OBO. If you pay asking price I will include two new napa gold oil filters for the Duramax as well.
Thanks.
