I have a 2012 Freightliner cascadia with a Cummins isx , putting out 450 hp. I bought the truck in August of 2016 with 497000 miles and it seems to be ok. Before I get to the question of ecm tunes, is there anything I should do now to maintain or maybe improve my engine performance by way of maintenance? I believe in spending a little now to save a lot later . Thank you.

This should be your first priority ...

That, and a thorough EGR tune-up, replacing all the old sensors.
