Wow, great numbers.
I drove the SRT to the mountains on Sunday and it was the first time I have ever checked the mpg. My 04 Limited got 27mpg @84MPH on cruise.
The SRT which has a 185mm pulley intake intercooler and ECU tuning to the max got... only 19.7 with cruise set at 73MPH (hit 100+ while passing several times) and used the air conditioner 1/2 the time off on the way there and on, on the way back.
I was not happy to find that out.
Enjoy the Ride...
