burnout/ spinning tire.
I know i will get ridiculed for this but oh well i have a warranty. i tried to do a burn out in my supercab with 4.6l 3.55 gears and it just cant do it. is the gear and engine not the right combination or is there some traction control or limiter built into the computer on the newer trucks? Even when i was stuck in wet grass yesterday it seemed like the tires would stop spinning right away almost like brake without me pushing on the pedal. ( stupid hankook tires. 
any information would be appreciated.

put the shifter into 1st gear
I don't know why, but in Fords, more power gets output when you manually select a gear in the automatics. Think it has something to do with Line Pressures.
My old Mustang GT could barely screech a tire in Drive...put her into 1st gear though and that bad puppy would roast the tires off the line.

My 2004 is just the opposite, i shift into a lower gear ( i.e 1st gear) and my take-offs are slower than leaving it in drive. some sort of protection for the drive train from what I have read somewhere.. Now, maybe with a tuner that function is disabled, but I'm poor, and don't have the tuner.

For the F-Series, dropping an automatic to a selection lower than (D)rive will automatically lower your available power. This is partially done so that you can downshift for tough take-offs with a full load or heavy trailer. It is also done to provide better throttle control while driving in places with limited traction and/or rough terrain. (I am sure there are other reasons.)

You still have the exact same HP/TQ ratings.
What Ford did was reset the Throttle Curve when you select 1st and 2nd gears. They only offer you 1/2 the normal throttle.
The 1/2 you have left is then spread out over the entire movement of the skinny pedal.
This gives you a really fine tuned throttle control for low speed applications such as towing, boat ramps, slippery areas...etc.
My Expy does the same thing. It is a really wierd feeling when I accidently put it into 3rd gear.

i did something like this earlier with my 09. this one road i go down has a few road humps in it. well if i roll over them slow and then nail it, the tranny shifts to first and kinda barks the tires and takes off. but if i manually drop it first and roll over them then take off, it lights them up and walks the truck around a little.

But, to be brutally honest, you will not have the same horsepower & torque curves. It takes fuel to create that power, and limiting the flow of fuel to the cylinders can drastically change your horsepower & torque curves. Granted, the overall engine design, electronics, and what-not still carry the potential to create the same power, but the fact remains that the performance will be drastically limited by placing the transmission in 1st & 2nd gears.

my 09 F-150 rental has those Michelins on it...they are pretty sticky. I've broken 'em loose a few times, but it took the entire throttle from a stop.
semantics...and you know exactly what I meant 
We said the same thing, but in different words.

My 2007 F-150 V6 5-speed won't do a burnout, but that's a good thing. I found out on wet pavement that it gets wheel hop doing a spin-out - I guess I'll have to put traction bars on it! 
. The funny thing here is, the engineers do everything they can to give the unloaded truck traction, and the guy complains because he can't do a burnout. Dude; it's not supposed to spin the tires - it's supposed to move when you gas it.
