Running empty, without Economax, 19. 83 (8856 miles). Running empty with Economax, 20. 84 (1580 miles).
Towing without Economax, 12. 35 (limited miles, 673 miles). Towing with Economax, 13. 22 (limited miles, 460).
Engine rattles just like the older Cummins, especially from 1700 to 2000 rpms. TST claims this will not harm engine. Sure hope they are correct.
You do notice more power. I still have not given it full throtle, son't want to kill transmission.
