I have a 4650 and a 1086. Compared to the 1086 the 4650 does have quite a bit less low end grunt but it isn’t THAT bad. I wonder if in your higher elevation it’s easier to get below the turbo. When we ran 2388 combines in higher elevations they fell flat and smoked coal black when we engaged the separators at a slow engine speed. Back here in Iowa at 1200’ elevation there was practically no smoke and we didn’t have to worry about killing the engine when we engaged the separator.
The only fuel economy records between the 1086 and the 4650 I have to go by is the Nebraska tests. According to the Nebraska tests the 4650 was slightly better on fuel economy. The 1086 was slightly better than the 4640.

In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
