Xs 2 I really hate the cruise control with the GDEThe one con that I found has to do with cruise control. Sometimes, the truck will just slow down a couple of miles per hour. It's almost guaranteed to slow down a couple of MPH if I mash the gas pedal to pass somebody and then let it drop back into cruise. I called Keith with my concern and he said that that's the way it's programmed in order get optimum fuel mileage. It should eventually go back up to where it was set, but it rarely does. Only once in my experience.
This is not a fatal flaw, but it sure is annoying when I have my cruise set just barely quicker than the guy I'm fixin' to pass. And then after I pass him, I let off the pedal and forget about it. Then the guy passes me almost immediately. And when I check my speed on the GPS, sho 'nuff I'm going 2 MPH slower than I was before. Because the tune had detected that I was using more fuel than I should and slowed accordingly. It's annoying and really aggravates the OCD in me. But, whatchagonnado?
