If you tell PHP your tire size (new) and your gear ratio (stock), I'm pretty sure Bill will program your
custom tunes with those values and you will not have to change anything. Not sure about the canned tunes.
Even if it does slip through the crack, these values can easily be changed (in the stock, canned and custom tunes) using the Custom Options menu (
http://forum.gopowerhungry.com/faqs-...ions-menu.html).
Even if your odometer is dead nuts (as I said above), your speedometer will still read high. And unless yours is better than mine, your fuel ecomony gauge (MPG) will never be accurate, or even consistently inaccurate. On average mine is .61 MPG high and has been as much as 2.21 high.
Hope this helps.
