I believe 2000 RPMs is about 64 MPH, but that is off the top of my head. 70 MPH is about 2100 RPMs cause that is what I drive to work every morning. Personally, with my Brenspeed 93 tune and no CAI, I get between 23 and 24 mpg's on a trip where I try and stay at 75 MPH. No idea what that would be with a stock tune.

65mph is right about 2000rpms like previously said.
Cruising at that speed on flat ground I get between 24 and 25. All stock, 6MT.
It doesn't seem to matter if cruising anywhere from 65-80 for me on flat ground I get about the same mileage. If drop it down to 55, i can get the advertised 26.

I'm 70% highway and I'm seeing 17-18 mpg with 3.73's. I average 70 mph on the highway and I'm not gunning it really on the normal roads.
If I hit the reset button on the highway and cruise 65, then I'll see 24-25... but that is not realistic expectations for day to day.

Well with 3.90s and a t45 18 city and 25 highway. And it pulls like a freight train now...mod motors are built to rev I guess... Oops... I didn't see what forum this was.

This car seems to be quite sensitive to cruising speed. I've been struggling to break 21, 22 mpg on highway, 19 with "spirited" rural road driving. Experimented on road trip today. Cruising for 15 mile stint at 80, computer indicated 21; reset, and same length stint at 70, indicated 23-24. At 60, indicated 26-27. Same highway, same day.
Obviously, EPA ratings are derived at the oil crisis speed of 55 mph.
I have GT 3.73 Brembo.

Yep, that's pretty much the same story here with 800 miles on the car so far and the kind of spirited driving i've been doing . Must add that it is a week-end driver and summer only.
