Just a word of thanks to all that have posted about their experiences in tuning their vehicles. I have been lurking here for a couple of months gathering as much information as I could before deciding on whether or not I should tune my truck.
On Saturday, I installed a MiniMaxx tuner and CAT/DPF delete on my 2010 F-250 King Ranch with only 5,500 miles on it. I was worried about voiding my warranty, but based on my research, I decided to go for it. Even though start to finish was about 3 hours, I was maybe under the truck for an hour. I ate up a lot of time going back and forth to check out this site for reassurance and direction.
What a change these changes have made! This truck flat out hauls a$$ now.
Again, thanks for posting your experiences. It really helped me out.
