I don't think it has much to with timing advance, probably more to do with the throttle by wire, no? The brake pedal sends an electrical signal to the ECU that determines that your truck is sitting still when you floored. It gives just a bit of voltage to the throttle servo so it opens conservatively so you don't go floating on tires in every direction.

Its just limited more in the sluggish trucks. I also heard the initial road test results with them spinning donuts and what not. It was just too much for most people, so they backed off the programming a bit and didn't allow the servo to open the throttle as much off the line. This is why when I puch it off the line, it gives me just a bit of gas until I am about 3500 rpm and then it lets go. Almost like hitting VTEC on a Prelude or something, except its just releasing all the throttle that your foot is demanding where it had been holding back before. With some of the mods and better gas I can spin them a couple of turns off the line, then it backs off to hook up and lets go when the ECU determines that at whatever speed you are now traveling you won't be able to break them loose.
