I have an opposite old fart story, involves GM 2 cycle diesels and road trucks though.
When the electronic engines came on line in the '90s it was hard to get old Detroit drivers to lug the new electric Cummins engines the way they needed to get better mileage.
When work traded off the old GMC with a 6V92 for a Volvo with an N14 Cummins our driver was always griping about the engine, no power, wouldn't pull up a small hill in Marion etc etc etc
One day I rode along to pick up a dead tractor and found out why. Driver was taking the Cummins all the way to the governor then up shifting which resulted in the RPMs being at about the shift point when he got back on the fuel. A few months later I went to pick up a 5288 and a 966 at a farm that had me coming back through Marion loaded. Got to the hill he complained about and found out he was mistaking RPM limits in lower gears with no power. Up shifted to a full power gear and accelerated up the hill with a pretty fair load on.
Took me a while to get him to stop driving that Cummins like it was a Jimmy.
