If any of the above is not used, egts climbed to 1300-1400 on any pulls up hill(but thats max), but follow the rules, and my mpgs are almost 2mpg better, and usually 1100 max up hill, and 800 average cruising. Once you find the sweet spot its all good.
I have to admit, we had about an 8 hour drive from Maine to South Jersey the other day, and I beat on it a bit pushing close to 70mph, A/C on, with higher egts, rpms, and my mpgs hovered around 9.2 mpg. Normally I can do low 11mpgs. Its all about how hard you push it.
