I have an '08 DC with the 5.7 and it has the most sensitive throttle of any car I have ever driven. It is difficult to start from a hill, because I literally spin my tires no matter how hard I try not to.
Background... I ran into a guy who said that he used to own my truck. He loved it but went through a divorce and it had to be sold. Well, he said that he had a programmer on it, or a chip of some sort. He made it sound more like a programmer, but I don't know anything about them. At any rate, I am assuming that the touchy throttle came from this.
I have had it for about a year and a half and my wife has driven it mainly as her daily, but I just got her a minivan and now the truck is all mine! I love the power, but the sensitivity is killing me.
Any ideas on how I can change it back to factory, or fix my current annoyance?
