I'm Awesome
1996 Chevy K2500, ECSB; Vortec 454/4L80E/3.73 on 285s.
With factory black box, tiny 245s and a cheap cat-back when I got it, I averaged 12-13 no matter what. Never towed with it back then so I don't have any idea what that would have been.
Now it's got an 0411; but due to some mechanical issues I'm working to resolve (needs a tune up, lock up kicks in and out of engagement at cruising speeds so RPMS jump around, fuel delivery issues etc.)
I get a whopping 8-9 MPG.
Towing my travel trailer and my open deck trailer result in 8 or 9, no change which is odd.
Last year in July I averaged 15 MPG cruising 75 on an 8 hour round trip to help my brother get his Dodge 3500. Not sure how I managed that.
