I was in the process of ordering an f5 DP tuner for my '99 F250. I am ordering it from ITP diesel and was filling out their truck survey when I came across the questions that make me wonder if I should be ordering the chip yet? First off they want tire size, right now my truck is stock height with puny 245 tires. I plan on adding a 4" suspension and 35's in the very near future. Should I put that I have 35's? They also are asking about tranny mods. My tranny is on its way out and I plan on doing a BTS tranny and torque converter when it goes out. Will I need to get my chip re-flashed when I get the BTS? What about if I add other mods in the future? Does DP charge to update your tunes when I do future mods? Should I order my chip now and have it made for my planned tire size of 35's? Please help, I want this chip very badly but not sure if I should order it yet? Thanks for any help!
