@60 mph, 17.3 MPG
@50 mph, 18.2 MPG

(Cruise control, about 10-15 miles each run, flat road elevation.)

Just posting, since I'll be installing the 180 deg thermo, Corsa, and DUB for reference. My average is 13 MPG @ I95 = 80MPH and every EZPass gate, WOT to 80mph, plus, Holland Tunnel and Manhattan traffic.

BTW, the billet antenna ROX.

so you get this mileage driving from SI to Manhattan regularly? that's actually not that bad (i get about 13-15mpg now in my G35)

NAW, not regularly. These were just test runs. I-95 has long strips of flat hiway for miles. Thus, I do these tests on all my cars, from time to time. New, the SRT8 did 1 mile less, per gallon, as stated above. But with traffic and my lead foot there's no way I get these numbers regularly. 12-13 mpg is my average. I do like to enjoy the power of this car, so my fuel efficiency isn't that great. But on an empty road, with cruise enabled, I can accurately track MPG. Well, as accurately as the computer does it for me. Even if it's less than posted (calibration might be off), it's 1 mpg more than brand new. So I have a reference point.

I drive through SI at least once per week. Maybe we could do a North-East meet sometime? Or Tri-state area? I live in NJ. Before we do, I have to finish my mods.. The DUB cai didn't come in yet.. And, some a$$hole stole my rear wiper. Ugh.
