I met a guy with a Ram Eco-Diesel that said it made a big difference on his truck, so I’m curious as well.
I figured that was partially the case, I'm also just going off the trucks calculated MPG which probably isn't real accurate?@jevalek77 don't forget you have now increased the circumference of your tires. Apply that ratio to your LOM and you may find some of your lost mileage.
I have verified that 60 mph is actually 62 mph. I'm not similar with FORScan other than I see it mentioned a lot on here. Can or will the dealership do that for me? The tires are the Nitto Ridge Grapplers 12.5" wide, so the are more aggressive. I had the lift done a few weeks before the tires were put on and noticed at least a 2mpg drop. It just feels like it bucks the wind a little more.@jevalek77 have you recalibrated your speedometer via FORScan since changing out the tires, or validated the digital speed of the truck to a GPS app on your phone? If you haven't done this your mpg's may not be as far off as you think. Dropping 4 mpg's for what you did to your truck seems drastic, unless you went with some mud terrain tires.
Yes the dealer can get it close but not spot on, they only have a few selections in IDS.I have verified that 60 mph is actually 62 mph.

Pedal Commander is easily removed, in fact you can hide it inside the steering column and run it via Bluetooth. It is nothing like a tuner, it only reads the signal from the accelerator pedal and changes it faster or slower tip in. Can't see why it would void warrantee or could even be detected if you hide it. I left mine mounted above the key, as I don't use Bluetooth. Service manager "Ram Dealer" saw it and even noted the settings. Rather he saw a "code reader" and thought it was a tuner, haha! Still, no issue with warrantee, as far as I know. The ( GDE Tune) is actually a complete reflash of the ECM. Some guys with Rams, elect to buy a spare ECM and have that tuned, keep original for "warrantee issues" . I take the Alfred E Neuman (what me worry) approach, had my original ECM tuned. I suspect when GDE starts tuning the F150's, you will see mpgs go up. I saw 2-4 more mpgs with my Ram.I have a couple questions... Will the pedal commander void my warranty? Is it detectable once its removed from the truck? How does it differ from a fuel programmer or what are the advantages on this vs. a programmer? I had EGR valve issue and there is still a loose screw in my engine somewhere and I would hate to run into warranty issues. However, I recently installed a small lift and 33" tires. Mileage dropped from 22MPG down to 18MPG, I should would like to find a way to get some of that back.
