Dave, my experience with engines is that you get no increases intorque or horsepower withoutthe attendant increase in engine & exhaust noise (which you then get toexperience whether towing or not).
Just curious, did your mods to your F350 result in more exhaust noise?If not, it makes you wonder why Ford woulddeliver a unit with 800 ft/lbs when they could deliver 920 ft/lbs with same level of "comfort." What did you give up?
