I’m used to Cats and my C12 will out pull this ISX. I’m trying to learn and appreciate all advice. Specifically 12th gear 11th gear? 12th an 1500 would probably put me about 66.

just my 2cents but 1700 on up hills, if you have a piro gage and intake psi gage use them low on piro and the lower the better on intake psi,i run heavy and a lot of hilly sh#$%#t so 30-35 psi on the up but other than that trying to keep intake to baer min. like 8-15 on most hwys. im learning it
and im doing better. head winds and big hills is a killer 4.2- 5 mpg on flats low or no wind 6-6.3
mpg
hope it helps you
