not for me.. i set the cruise around 90 going across Canada and it stays around 17mpg..

I live in the South, the speed limit is already hauling butt. Add 9 to that and you are cookin. I don't even have to break the law to run 80. Run 55 around here and you'll get run over by a semi. But yea, if I ever was somewhere that I did 55, for sure, better mileage.


Now that I think of it, a couple years ago my wife followed me in the 350, I was driving the biggest uhaul and towing their biggest trailer - loaded to the roof. She got 22mpg over 900 miles. I think the uhaul got like 4.




For some reason the Older trucks get better mpg with that smaller turbo

yeah no doubt.. that also created a big tunnel for your wife to draft you in. lol
I'm running 295-70-18 front tire psi 50 rear 45

Tyrant Race 14.17 overall in 400miles going to CA

Gearhad race 14.79 mpg overall in 400miles coming home from CA



BUT, going to CA you have to drive it hard. You have Semis trying to pass other Semis, so it's WOT passing around them, this is constant. Worst is when they cut you off to pass another semi uphill. You slam on the brakes, then I precede at WOT to pass him in the slow lane (there's plenty room to make it in front of him)

Getting stuck behind a semi trying to pass another semi going uphill is NOT fun...


And don't get me started on cars not going back into the slow lane and they just stay in the passing lane going barely the speed limit. Men in mini vans are the complete worse. Idiots try to beat you when you pass them... Ha...


This MPG is also with traffic after I got into SoCal.


I have never been able to set cruise at 80-85 and just go straight on flat hwy till I need fuel again.

I'm on factory tires with 3.55. I and almost never in thin enough traffic to run the cruise. It's not as bad as you face, but bears a slight resemblance. Your mileage probably isn't that bad considering the driving style and SoCal traffic. GH and Tyrant are bound to be at least as good as my old tunes, probably much better, since IDP stopped messing with them after the tree hugging jack booted thugs gave them a not so friendly ring.
