Angry RPMs too high

F350 on 20" rubber with 355s rus 2000 rpm at about 70mph. I don't like to run at such a high RPM.Would be nice to run 70-75 at about 1400-1500 RPM and would be easier on fuel as well.

unless you drop the rear end ratio or do a gear vender over drive you wont see those rpms with factory 20's. and for what it's worth i am just under 2k at 75mph with 3.73's & 35" tires.
