whats goin on, well i bought me a programmer for my truck. mainly for the drastic gear change, as well as the tire size cuz right now when im going 70 im showing 86 on my speedo. its the Granatelli version of the Diablosport predator. idk what the differences are b/w the regular and the G-telli, but i got a good deal on it used. i know this is for me f150, but anyone have one for the rangers? satisfied?
