lucerne tractor Posted April 20, 2012 Share Posted April 20, 2012 I've been running the Mack from 1400 to 1740, wrong!! I found this on the computer on the dash. Mack says lug it to 1200 then split or shift up to 1400 or 1600 and lug it again to 1200. Up shift at 1600.Well, I have run two loaders up through the hills of Pa,NY, and Ct. the second one was heavier. I used Macks methods the second run, here are the results.It crested the hills at a higher speed 2 to 3 mphThe turbo boost was 3 to 4 pounds higherThe engine heat was lowerThe pyrometer heat was lowerThe fuel milage was betterSeems there is nothing but good from the 1200 to 1600 or down from 1400 1600 to 1200 recomended cruise rpm 1700+ or - 50 rpm. Mine runs 1650@ 65Sitting in a NY truck stop, headed to Fla via 81 and 84 one more time.
