Ok everyone, List the best Mod you have done to your truck to date. By this I mean some sort of performance mod that you have found that worked best for you, also give us the worst mod that you have done. Maybe we could all learn a thing or two from eachother and get ideas for future mods. Please dont list mods such as Blowers,nitrous, or a stroker motor,.... we all kno these are great mods but I would like things listed that most everyone on here can afford and do themselvs.
The best mod to date on my truck would have to be a tie between my exhatst and the Underdrive pulleys.
I also want to add that the IAT sensor mod was a waist of time, I felt nothing from this mod.
