My idle clip's with this cam. This is after many hours of driving on Las Vegas Blvd. It's normally a bit smoother than this even.

It's very nice once it's tuned in. Headers and more stall would really get me better numbers though. With my tire height being as tall as it is compared to what others run at the track my track times don't look as good as what I have to compare it with.

Was the idle difficult to get dialed in?

Your track times still look pretty good to me.

Not to get off subject but I am down by the St. Joseph area in the Southwest corner of the state, not too far away from you.

Ah, very cool. I drive through there fairly often. The idle wasn't too bad, but i went through alot of time in making sure everything was how I wanted it. I'll post up some screen shots of the tune later. Lots of idle timing helped that.

Yes timing was a big issue for mine too. As far as idle quality and low RPM torque go. I have some false knock still, which I am told is common with a 1999 Operating System.
