Is this correct? mine is currently in the 1.5 to 1.7hg range, so just trying to get an idea of when I am gonna need a bit of maintenance to these.

Yep, that is correct, how many miles on the cans, or hours since the last bake? Is it a DPF or SCR? Do you do regular EGR tuneups? You get up there in the 3's it's time, me I would rather catch before it gets there.
