No mods....just stock SRT6 but driven gently in the slow lane during San Francisco commute traffic. Some rare occasions late at night where I can floor it and get up to 80 or 100 briefly before letting off but that should not impact my gas mileage that much per tankful. I think 22 - 23 is average from what I've seen posted.
