Was curious if anyone has ever used a “tuner” or something similar to increase the fuel mileage of their tow vehicle. I know tuners can decrease mileage but i don’t have any experience with this type of technology to call it anything other than tuner. I have a 2000 Ford Expedition 5.4 Triton and towing with my previous boat I was getting 13 mpg. I recently purchased a Nitro Z9 and I’m down to 10 mpg (Bigger, heavier boat). Any miracle technology out there worth trying? I know I’m not going to get huge increases but even a few mpg would help. Your thoughts?
