I just want it to be said that a different size seems to work best for each engine.... I put essentially the same cams in several cars adn they each took a different drill bit. Start really small and drive it for a little while before moving to the next one. The car does adjust itself over a day or two of driving. On the SS I went too far because I didnt drive it for awhile between each size, adn I overshot it by aways and had to start over again with some JB weld. On the C5, I started off slowly, drove it a couple days between each size, and now its totally spot on. THe trick is to watch the speed that the engine turns when you are coasting at 10-20 mph with the clutch in. I dont think thats as adaptive as other idle #s, and getting that around 900-1100 rpm is the trick. Once you get the coasting RPM at that level, you know the rest of the system will be happy.

really you just gotta start small and go up till the IAC count is where you want it
