You can change that parameter yourself when you get it. But if its stock wheels/tires it will not need a change.

Yep, stock you should be OK. If you do change your tire side there is an optional parameter in the tuner to change the tire rpm's to adjust the speedo. I had to do this when I went to 295/45's in the rears.

I'd call and let them know in case they haven't shipped your tuner yet. Otherwise, as they said above. You can adjust it yourself. Just get the Revolutions per mile for your tire from the manufacturer's website or Tirerack.

are your 18s stock?
