No worries. I just wanted to clarify why lower RPMs are desirable, from an engine longevity standpoint. I have read already on this board where one ecomodder tried to do lean burn (in the form of a throttle-less gasoline engine), and ended up destroying their engine.
That reminds me: Y'all realize that a diesel engine is by definition a lean burn engine, right?
