I listed all the mods in the thread "oil is King". I hate to refer to that thread but it's a long list. Yes it has air lift bags on the rear with an on-board compressor.

I think I listed all the mods. This truck will run out at the red line on the tach. With the Jet, It goes into lockup firewalled at 80 mph. It will flat smoke the tires and I run 305-75-16 All terrain TA Ko's. The one two shift will chirp the tires and every shift is very and I mean very firm, including lockup.
We put the truck on the dyno (My day job employer has a 2000 hp dyno that I can use)
The Ford made a little over 350 ponies at the rear wheels at an indicated 60 mph in direct (we locked the od out). The hard part of the dyno run was keeping the truck from jumping as it shifted. We had it chained to the floor through the receiver hitch.
The best part...I average 20.1 mpg highway and I have 4:10 gears.
Being an old fart, I don't do the stoplight thing, but if I get goaded a little, I don't mind mopping up a Dodge or a Chevy or another Ford. Not very often though, I already know I can wipe 'em out.
Remember, when a manufacturer rates the horsepower and torque of an engine, whether it is Ford, GM or Daimler, they rate Flywheel horsepower. Real world horsepower is what the rear wheels put to the ground. Your average driveline loss is about 20%
I also haul hay with it. I have a tandem axle gooseneck that I regularly haul 17-20 round's on. I was concerned about transmission temperature, but it never goes above 210 degrees.
