I don't know what size tires you had stock, but if the new tires are taller, your speedo and odometer will be off. On e you correct it (with the tuner you are talking about) it will reflect actual numbers. Mine was off by about 4ish percent when I went from stock STX 18s to stock FX 20s. My MPG dropped due to the error in the odometer. I bought a tuner to fix the speedo and odo, and my MPG are now closer to what they were with stock wheels and tires.
