I have 285's on my '03 Dmax and would like to adjust the computer to calculate milage and MPG correctly. How can I do this myself?

Sandman 11-02-2006, 03:19 PM Some of the tuners can do this. My Quadzilla can adjust for gears and tire size as well as removes the top speed limiter....amongst the power upgrades and code scanning ability.

Like Sandman said, best bet is probably a Predator, Quadzilla or other tuner that can adjust for tire size. | ||
