Mine is a 2001, crew cab, and the reason the GVWR is 6600 on mine is because of the 3:55 gears, If I go to 3:73 it will bring it up to 6850, and I just may do that. The Stock 5.4 is a good engine, I just have a bad habit of liking to play with things, the problem is the weakest link is the transmission and U Joints when you put a lot more power than they were designed for.
Do you run yours in overdrive on flat highways?
Terryallan; thanks your your input, obviously I have never used a WDH, it took me a little time to figure out how it worked, I probably spent ten minutes looking at one at the dealer until some nice guy explained the geometry and how it worked. One thing I noticed is the rear mounting bolt does not protrude through the frame, I was told so the thing could shift or move, that seems like it would defeat the purpose.
Nope. Just turn off OD and let it run. As you like to tinker. Then you already know the engine will be much happier in 3rd gear turning RPMs closer to it's power band, and using all the fuel being supplied to it. You may in fact notice better MPG in 3Rd as the engine will be, and mine is MUCH happier, and running free, and not lugging trying to hold OD. Also the transmission will run cooler. It will run all day and be very happy with OD turned off.
