Any of you guys running 18" wheels change the setting on the SCT tuner to correct the speedo. Im looking for the right setting. I believe it has it in rev/minute or something along those lines. Thanks.
Go to nitto's site, get the revolutions/mile and then get into your tuner and set rev/mile to the closest number, but dont go over the number. that will get you your most accurate speedo setting. It will read a little faster than youre actually going, like maybe .00002mph faster than youre going but that way its not showing that youre going slower than you actually are. you catch my drift?

Use this and put your tire size into the prompts and it will come out to 787 revolutions/mile so 785 would be your closest bet. 275 40 17 tires are 810 according to that calculator. The guy is a regular on Mustang Forums and is some sort of engineer genius.
Called AM and informed them of the issue and they said that this issue will be taken care of as soon as possible. :thumbsup:
