Goatspeed

I noticed that if I let my car sit for a while, or even on cold starts-ups the engine jolts up to about +1500rpm pretty voilently. I almost hear it seem to ping for a second, it then settles to about 1k for the typical choke period or comes right down to +500 if it is already warm.

Is this just how this high performance engine starts? Its almost like its WOT for a sec, a gush of gas is sent into the engine before it settles.

Any thoughts would be appreciated.

sounds ok as long as it settles down around 1k, sounds like a normal wind up

normal, it revs up a little on startup.
