My grandfather has a 2002 3500 auto 2wd and needs a chip for more MPG and towing is the XZT a good chip for it or do you guys suggest another?? Thanks

 

If you strictly want mileage and can hang on for another month or so I would wait for our new XZT we are going to be coming with. It is adjustable, easy to hook up and will get better mileage than the current one because of the timing we do. It also has some other cool stuff.
