Want towing comparison between OBS 7.3 and SD 7.3

Mild tow tune, gauges (especially EGT), intake, 4" exhaust and you should be sitting pretty, that is if everything is functioning properly. You should have no problem with close to 500lb. torque.

I would have no problem driving a P.S. 7.3 OBS if well maintained, running properly and the above mods. They are sweet looking with an awesome engine, just too doggy for me bone stock.
