Any suggestions as to the best programmer/downloader to improve fuel economy? I currently have an Edge EZ and I truly can't say it has made a big improvement in my towing fuel economy. What do you have and what kind of improvement have you seen?

 

Smarty or Smarty Jr.

We have also had some good luck with the TS MP8

 

Check out Quadzilla's Products they will give you really good mileage I have had their Mileage Max, XZT, and now have the Adrenaline and all of them have done great with mileage. The Adrenaline has custom tuning and so far I have seen good results with the little bit that I have tweaked it, can't wait till I really get it dialed in.

 

The Adrenaline for the CR is looking very promising
