Sold my 6.0L and have the tuner for sale. This unit was purchased new in 2004 and has only been used on my truck.

Race, Street and Tow are the 3 tunes on the unit. I do have the tunes on file as well, so they can be sent via email if you want them that way.

Unit has always worked perfectly. Was purchased from Doug at GoGoDiesel.com and maintains his tunes.
