About 13 around town, a little better than 20 on road trips. Comfortable 15 +/- all around....... First road trip to Myrtle Beach from KY we hit more than 20 several times, but never reached 21..... Good luck! Oh yeah, premium only.

yea around 13 or 14, not to great but on the highway i get around 23, 24 (with cruise controlat 70) and if i go around 65 it reads 25 and 26, the CAI and tune does wonders along with massive hp gains
