My 5.4 is slow.. But it'll out tow any F150 in our generation, it would probably make a newer one have its feeling hurt while towing. I also would never own a F150 with a 4.6 again. I had a 03 2wd SCab with a 4.6 and even after swapping gears to 4.10's it was still a slug.

It seems as though it would be, but i had a 94 F-150 with 300 inline 6, and i could out pull, outrun, and use less fuel than the 302 V8. Made by same company. Every engine type has its quarks and even every engine within that type does.
Had a buddy in college with a 96 reg cab short bed with headers and dual exhaust on his inline 6. He still couldnt keep up with my Reg cab long bed. Both 4wd. Just depends on how they were taken care of and how they were broke in.
Friend got a 2008 f-150 crew with 5.4. He broke his in towing and i think its because he did that, he couldnt ever get more than 14 MPG. But it would out tow alot of other similar vehicles.
I dont have any proof to prove or disprove what anybody or myself is saying, but it makes sense to me.

It all depends on how it is driven. These newer vehicles have what is called Adaptive programming. If I reset my PCM and drive like I'm driving Ms. Daisy it will be a slug. But if I drive it like Mario Andretti It doesnt like to keep the rear wheels planted.

I have an 03 f150 with 5.4. Would i be able to reset my PCM? My truck has always been a little sluggish compare to other stock's. If so how do i do it?

Yes disconnect both battery cables. Touch the ground and positive terminals together for 30 seconds. YOu have reset the PCM, and it will activate the relearn procedures. It takes up to 100 miles before it turns off. I drive mine like I stole it, until it has relearned itself.

I think its cool that they have started revisiting some of the old engines like the 302. I hope they revisit the straight six. It would be a beast with all the advancements in technology, if they can get a 3.5L dual turbo to hit 365 HP, i dont see any reason why a single turbo 4.9 inline 6 could match it with better torq or exceed.
I kick myself everyday for selling my old truck, but i do enjoy my new screw

Also when making a statement with subjective terms like "extremely efficient", you should first define what it is that you consider to be "extremely" efficient so there is some sort of number to compare to when arriving at the conclusion something doesn't meet that criteria.
What you have said is extremely vague and really doesn't have much, if any, meaning.
I've also just read this on wiki:
"An inline six engine is in perfect primary and secondary mechanical balance, without the use of a balance shaft. The engine is in primary couple balance because the front and rear trio of cylinders are mirror images, and the pistons move in pairs. That is, piston #1 mirrors #6, #2 mirrors #5, and #3 mirrors #4, largely eliminating the polar rocking motion that would otherwise result. Secondary imbalance is avoided because the crankshaft has six crank throws arranged in three planes offset at 120°. The result is that the secondary forces that are caused by differences from purely sinusoidal motion sum to zero."
