I always felt like it was the shifting pattern set by the computer, but Ford always said, "Nope, everything is normal." The chip made a little bit of a difference, but not enough to warrant having to switch to Super U/L for me. The exhaust is one thing I didn't do. Maybe that is the big factor for the 5.4. Who knows... For the money I shelled out on my first new vehicle, I just wanted it right. I was pretty bent. At least I don't have to worry about it anymore. I have a ton more power and much better fuel econ

Diesels are a completely different story. You'll see a BIG difference.

My '99 F-250 (see signature) pulls better than an F150 and holds the road better.....It should. It's heavier. It cruises easily at 70 mph without a trailer. It's the 2 valve, 5.4 liter. With 4.10 gears it suits me fine. Gas mpg is 14-16. I've read that the V-10 gets about the same. So, I'd go with a V-10 if I was in your shoes, especially if I was in hilly terrain and towing quite a bit. But, in my mind, the diesel would be the ultimate in towing performance. If you are talking about accelaration from a stop light, I wouldn't pit my F-250 against those Silverados. But, old guys quit that stuff a long time ago.

Keep in mind your talking about an almost 8,000 pound truck with the rough aerodynamic properties of a brick. If you want fuel economy, buy a light, little car. If you have work to be done, get a Super Duty.

if a PSD (at a whopping $5K) don't fit your budget, or needs and your wanting to stay with gas..........go V10!!

The PS 6.0 with tranny is about 8K option on 06 (on my sticker anyways)
Just bought a F250 2006 PS 6.0 with torqshift and love it! Getting around 20 on the hwy, 14 in town. Just installed the Edge EZ and will see if it really improves MPG. Didn't need the extra HP or torque but it does make the midrange unreal! Can't say enough about this truck!
