Mentally Unstable..
you do that with a 3406 and it will reward you by coughing up a cylinder liner.
Seriously? All the old truckers and even a service REP with Cat told me that the BEST way to get mileage out of her was to lug it like hell. If I thought I should downshift...don't. I have lugged that 3406B so much over the past year or so it's not funny. 1300RPM and lower, hell, I have let her come back to 1000RPM and kept feeding her fuel...not on the rug, but a decent amount to maintain boost and that thing never ONE hacked up a hairball lol.
I try to drive her between 1000 - 1500 RPM in the city, but due to lack of gearing 2000 - 2100 is 60 MPH.....it SUCKS!
