Dang, someone just sold a superchips tuner on here not too long ago that would have worked for your truck. I'll keep and eye out for you.
Although they only sold it for not much less than you can get it brand new from one of vendors here on the forum. You can get a new superchips 3865 for ~$286 with our forum discount that our vendors offer.
