im thinking of getting a tuner in the next week or 2 cause my tire shop called and im getting my larger tires on at the end of the week and i really dont want to have the speedometer be off for to long. i know you can do the adjustments with a tuner to fix it i just want some opinions. im thinking about getting the DiabloSport Predator U7157 tuner CLICK HERE
ive heard good things about it from a few people. does anyone else have a suggestion or review on this tuner? ive called every ford dealer within 30 miles of my house (about 5) and none of them say that they will calibrate my speedometer at all because of some bs about it being illegal or something stupid. if i could i would go that way. but yeah any comments or suggestions would be appreciated. i reall dont want to spend this much money but i really dont want to driving around with an off speedo messing up my odometer. it just really bugs me. thanks in advance.
