Great fix for the annoying AFM
I pull a 5300 lb travel trailer. Even in tow/haul mode the truck would lose power because of the AFM. I installed the Ranger AFM disable device the day after I received it and left for a camping trip (200 miles one way). There was a noticeable difference in power. No more 4-5000 rpm downshifts. Only a few times did it rev to 3500 rpm. I mostly drive with cruise control. I think that's the reason for the few 3500 RPM's.
Installed two presets one premium one regular on engine tuning. Installed the rest of the options the same for both. Ran each preset and could not tell any difference from my stock settings, both preset gave me 0 gain on mpg. Instructions very hard to follow not as easy as 1 2 3 and time for programing is not 15 minutes try 45, extremely slow in reading and writing the program. Going to change options one more time but doubtful of out come. I was hoping my 2013 Fort Raptor would have gains.
