Towing with a Powerstroke 7.3L (expectation/realistic)

Like others have said, its all about the upgrades and tune on the 7.3

For $1000 you can get ceramic coated bellowed up pipes, Riffraff or WW2 turbo wheel, and bigger exhaust. That takes care of most EGTs. Now get a good tune that is changeable on the fly like the PHP Hydra or DP Tuner plus the quiet Ford factory AIS airbox for another ~$350 and you are set.

Those are the mods in my sig and I can pull 7500 lbs at safe temps with the 80 hp tune up 8% at 75 mph all day up at 6000 ft or more.
