2100 on the NA and 2500 on the SRT. Best efficiency with a standard factory tune.

I get over thirty on the NA and about 28 on the SRT when cruising onthe Interstate. My wife and I take seperate vacations together. Her in her SRT, me in my wimpy NA 6 spd. On our last trip to the Smokies (Dragon Fontana run) we compared our milages.

Last weekend we went to Southwest MO in her SRT. 363 miles on a tank before the light came on. Mostly driving at 65 MPH.
