m6 with 3.90s and a 408 with stock heads (make 470/470) I got 25ish on the highway, SD tuning.
In town and start and stop, it sucked, but it was start/stop every block.
Gotta pay to play.

im averaging 16 MPG according to my DIC in the vette... 6 speed M12 tranny mine is a fairly wild cam setup as well. i drive it every single day to and from work and play.
on the freeway i average roughly 28 MPG... (im not lying i can take a pic of my DIC hehe) but of coarse the vettes aerodynamics and weight paired with a 6 speed ='s awesome mileage.

Its an M6. I think something WAS wrong. 383 is being built now and was just wondering what kind of mileage to expect. As long as its not any worse ill be pretty happy considering the HP increase i'm about to enjoy.

Just checked mine last week. Averaged 16.67mpg thats red light to red light and some interstate driving. Car has bad 02's (keeps throwing codes on them) And the trans slips like hell in 3rd and 4th. Once I get new 02's Im switching to SD and see if that helps any...

1 vote for SD.. i LOVE it.. i drive in rain storms and all sorts of weather and never have any problems.
also nice because you know if you tune it good that its just going to pull striaght off the tables you KNOW are working good. dont have to worry about a bad sensor screwing with your tune

BTW I love Ogden, My mother used to live there and it is really beautiful country around there. I used to go up every year to Powder Mountain and snowboard. I would love to live there one day with the lake in the summer and nice mountains in the winter...sorry had to brag about your neck of the woods though.

I get between 12 and 15, (depending on conditions) 403 ls2 with an auto and 3.70 gears with a fairly small cam. (23x / 24x) It's not really much worse than my H/C car with a stock bottom end and 2.73 gear. I'm guessing the gear has about as much to do with it as the bigger cubes.
