Even Works With EFI Live
I bought this to fix my speedometer on my 2008 Dodge Ram 2500 Diesel. I was running 37" tires and went to 35" tires to fit a spare under the truck. I couldnt adjust my speedometer with EFI Live that I already had, so i bought this. It worked perfectly without having to reset the truck to stock. It took me a while to get the truck perfectly calibrated but now its dead on with my GPS.

I had my doubts about this Tuner but I was wrong. I have had this about 3 weeks now and initially I could tell the quicker take off. Then I went on a Easter trip to Missouri (500)only this time I was getting 20-22mpg/ 16-17 @75mph and I still had kick. To Missouri and back I averaged 20-21 mpg and was happy and the power continues to improve. Now that I have installed a K&N filter I think things will even get better. I would definitely buy this product again.
