I read a while ago in order to get the best mileage was to run under 600* pyro, and under 8 pounds of boost.. I did this coming back from the coast today. It seemed I could go either 60 or 70 at or below these temps and boost.. What speed, pyro, boost do you guys recommend for maximum mileage?:thumbsup

its also time you are paying for as well. take for instance a 1000 mile trip. at at 55mph average you would conclude your journey in about 18 hours and 15 minutes. now at 65mph you will end at 15 hours and about 20 minutes. now do 70mph and you just cut another hour out of the equation and end at 14 hours and 20 minutes. if you can justify the 4 hour and 5 minutes longer it would take you to go at only 55mph then do it.

now let say at 55mph you get 20mpg. that 50 gallons of fuel to get you there and at $5 a gallon thats $250. now at 70mph you get say 16mpg and you used 62.5 gallons of fuel and at the same $5 a gallon thats $312.50. now to get you to your destination 4 hours and 5 minutes quicker it will cost you $62.50. is it worth it ? thats up to you. for me yes. i can be at home sleeping ready for the next days work and not tired.

oh and yes i am REALLY bored this afternoon. no parts to install on either my car or truck :(

and for me i seem to get the best mileage at 70mph.

Thats some impressive math skills you have!!:beer Im thinking if i Keep my foot out of it:peelout Ill be better off than worrying about the speed. I just love coming to the bottom of one of those mountains with the passing lane in it as some yuppy is driving his new beamer at 50 in front of me and as soon as the double lanes open up, i have smoke and speed blowing by his 5 series!!!:T::rof I start singing that song, "I'm just your regular joe, IM AN :butt: HOLE!!!!':thumbsup

I get paid on piecework so if I get to work 15 minutes later/5days a week by slowing down 10-15 mph I would lose the money it would cost me to fill my tank for the week. Roughly 150. There comes a point when time has to trump MPG. That being said I love my Cummins. It gets 6 mpg more than my powerstroke did on any given day.
