2005 PSD Acceleration Lag
While test driving a 2005 F250 6.0, I took a left at an intersection and much to my surprise, when I hit the pedal, the truck slowly crawled into the intersection, in front of traffic that I would have otherwise beaten easily, and after what seemed like a while (probably 2-3 seconds at most), the truck took off without adjusting the pedal. And it really took off. A little scary on both ends. It did not do that any other time during my 30 minute test drive.
It must not have bothered me too much as I ordered one that day, but what the heck?
I've seen a few other remarks about that here ("some have it and some don't") and was wondering how many people are having the same issue with their 2005s.

There's turbo lag, and then there's computer program induced lag. Some of the lag that folks have described sounds more like the computer waiting to give throttle for some reason.
An example of this is if I were to back out of my driveway and then shift into drive and punch it while still rolling slightly backwards. The truck won't actually give any, or much, throttle until the backwards motion stops, then it takes off.
I'm wondering if for some reason this same thing is happening?

I'll try to play with it and see, but when driving normally I don't notice any delay.

I'm just guessing here from far left field, but could it be defueling to keep from dumping the drivetrain out in the road? You know let it get rolling a little before pouring the fuel to it.

It will not matter how much fuel you dump it at takeoff; without turbo boost it is simply not going to build significant power. Extra fuel will help reduce the lag, but only to a certain extent. At a certain point, more fuel will do nothing but make excess smoke.
