Check for vacuum leaks while you are under the hood. A vacuum leak could make the idle higher than normal. I'd look for any leaks before sending in your PCM to be tuned.

First thing I checked for were vacuum leaks and couldn't find any. I do know that it has been idling like this since I first got it. I am thinking that with the cam, the previous owner had it set this high. Wish I could figure out which cam was in the damn car.
You could always try checking with Chris at Wichita dyno or with aknovaman up near Topeka. They might be able to help check your tune.
you need do make shure there in no vacume leaks first and rich running car can act like a small cam if it is loading up
