What boost do you hit @70?

......running on the level, no wind to speak of @ 70 in my 4x4, 3.54 gears, 285X75x16 BFG's AT's, I pull between 8-10psi on the gauge. Just curious how others do.......

As long as I'm not accelerating and the ground is flat my boost is 5 or under at all speeds.

6-8 most of the time, but at 75 on i-80 taking on 30 mph winds the other day with the a/c and cruise on pulled 18-20 up hills. The truckers tend to notice you passing them whistling like this!
