Off the line a manual will eat an auto of similar power to weight.
At 20 and up very little in it
Maybe yours Mart 
Nope - mine is sluggish up to 20 then goes well, same as every 4 speed auto I have driven.
QUite simply you can't rev up and dump clutch on an auto
You can have it in the v6 powerband before moving. I'm not saying its good for the autobox, and boy does it stink after a few times in quick succession, but it does help the auto off the line. Still wouldn't help it beat a manual to 60mph, or 100mph though - auto gears too long 
Do you mean dropping it into gear while revving?
I suspect more 'left foot on brake, right foot on throttle, give it some until the torque converter is
almost at it's stall speed, take left foot off brake, stamp on loud pedal'
(I don't recommend that if you value your transmission, mind..

)
And TB - is it just me, or is the 'traction control' quite .. poor at controlling traction? At least it seems to be in my 51 plate - it's very good at spinning the rears from a standing start, though!
