After modding my truck with an Air intake and a new muffler, everyone says get a chip next. Well i have some questions to ask before i bump to that step. First, i've been looking at the different options and i've narrowed it down to either Hypertech or Diablosport. Hypertech is just really popular but i hear you have ALOT more options and little things you can change/do with the diablosport. So a question is do you have to put the tune back to stock with the programmer if you want to tow something? Thats one of the things i'm worried about is if the engine is set to a mode by the programmer and i go to pull something am i F*#$ing things up by doing this? I guess thats my main question for now, but if anyone can commment about programmers, how its worked for them, or suggest anything to me about it, that would be great, & thanks ahead of time for anyone that responds!.
