Agree with Greg, very comprehensive explaination. Greg has obviously not opened a Red prior to typing that one, mmm. The man certainly has a way with words.
Also, the throttle discs MAY be out of time/synch, and this will have 1 engine doing what is does before engine 2 catches up. Bearing in mind it is a "double six", and the firing order makes it that way, so the synchronising of the throttle discs, particularly OFF IDLE synch, is critical.
The dreaded "black goo" inside the throttle bodies will also reek havoc with off idle performance.
Then comes spark plug gap.
Then the list gets picky, and loooooong.

I am concerned as to why you would blip the throttle on a cold engine. I would never do that unless it isn't running well. Not having a V12, I really do not have an opinion as to the necessity of doing that.
My 4.0 1996 does not need blipping. Cold starts it goes to 1,000 rpm for about 5 seconds and drops to 800 rpm and to 600 in under 30 seconds. Are V12 engines more cold natured?
