At highway speed on flat ground, not average. His Ex cab is on the light side also. Non the less its still good mileage.

A round trip from his house to the track and back making 5 passes got 20mpg at 4500#. I mean, is there any way else you can slice it up to discredit it? Is it the wrong color maybe?

Wasn't discrediting anything, however when comparing fuel mileage weight means allot would you not agree? There are standard cabs that weight more then that. There is allot more to the fuel mileage figure then CI, thats my point. In true fashion I knew you would provide more info if I stated that as you are never one to shy away from getting defensive. Tuning and speed can make a 20mpg setup see 15 and vise versa. 20mpg out of his setup is impressive, wasn't arguing that....

So the 1.25 miles at wot, idle in the staging lanes, and 5 burnouts is included in the 20mpg? That's pretty damn impressive!

On e85 it got about 12. Think it could have got 14-15 if I worked with it.

On gas with the blow thru it got 14
