These are excellent units for reprograming your vehicle computers and give great results. I use them on all my vehicles and have always gotten great results. It makes towing easier and helps fuel economy. It makes it possible to change the programing on your vehicle that the dealers will not change even for a charge. Why they refuse to set them up to run efficiently on regular fuel is no suprise but you can fix it yourself with these units. Excellent buy for the money. Would recomend to anyone.
