Added power, improved intown/highway MPG, corrected for tire size, however it failed for increasing shift points. Shift firmness definitely improved!!

I put in the 93 octane tune into my truck. I ran it and the motor was skipping and missing bad. I went on the Diablo forum for Ford and found in the model years 2011 and 2012 you had to replace the spark plugs and gap them closer together. I installed new plugs gaped at .029 and installed the 93 tune. WOW! Very noticeable difference in power & throttle response. My automatic 4x4 4 door truck chirped when I hit second gear and it does not break up any longer. Well worth the money and trouble.
