Those of you driving by boost...

[dhirocz]

What are your typical goals when driving by the boost gauge? I'm trying to teach myself to drive the truck for mileage now, rather than speed.
I'm driving back to Savannah tomorrow from VA. So far so good. Mileage driving back has been very good...should have some good numbers tomorrow. I see I can drive at 2.5-3.5 lbs, and can maintain or slightly slow down going up hills at about 5, but that is also with an empty tank trailer. This is getting me between 58 and 62 mph.
What boost numbers do you shoot for when loaded upwards of 80k, generally?
I'm trying to break the habit of driving against the speed limiter with my foot on the floor or using the cruise control.
