After having it on my 2010 fx4 for about a year it now has dropped its power the truck feels slower and it doesn't accelerate like it used to back when i just had installed the programmer, I did the update but now it asks me to set a fuel wot?, and an idle rpm, the fuel wot only goes up to 200 no idea what that is, and the idle goes up to 350 which is too low I was thinking to let it idle at 1000rpm but it won't let me. anyone else experiencing this or have any thing that might help me?, at least explaining what fuel wot and idle rpm should be at, I've done research but nothing that helps.
