Almost no power increase in an mode. Fuel mileage increased about 1mpg while towing. I may change it out for another brand.

I have it set on the high setting and am averaging 20.1 mpg in mixed city and highway driving. Who would have ever figured a 3500 dually would get 20 mpg Great product Was this review helpful to you? 2018 Dodge 3500 Dually December 30, 2019 Reviewer: Jan Moyer from Tetonia, ID United States Slight increase in mileage, expected more But it’s early, great increase in power.

Have not noticed an increase in mileage, but that may be because I keep pushing accelerator harder to enjoy the power.

On stock I averaged 9.9 mpg with total weight on trailer and cargo at 18000lbs. Ran another round on 30hp bump averaging 12.1 mpg. Once again another set at 60hp bump an impressive 13.7 mpg. I also looked at how much it cost to refuel during my trips. Filling at same stops on the (9) day run. On the 60hp I was saving $13/fill up vs the stock mode. Based on this information I am convinced the savings will pay for it self. I’ll continue to use the 60hp bump with my 40’ gooseneck trailer and I’m curious what it’s like without the trailer but with these numbers, I have little doubt that I wouldn’t continue to see vast improvements in mpg. This far A+ I’ll continue my determination after putting new tires on truck this week and see what gains will come with low rolling resistance tires and the unit combined will accomplish!
