In Neutral (manual) I have no problems what so ever. The idle is rock steady. The only problem is when the rpm's are up to like 3k and I stop short. This is where the dip occurs. I dunno if it is even a problem as I don't remember if my car did this with the stock cam in there. Another situation is just reving at idle. I was trying to have the revs come down and stop perfectly at 800 rpms. Mine dips slightly below and bounces back to 800. Again im not sure if the stock cam does this as well.
The more I played with the decay values the worse of a surge on the comeback (back up to 800rpm) I got.
Also my IAC count at idle is around 80-90 fully warmed up.
I dunno I think Im gonna leave it as is and start tuning the part throttle and Wot stuff.
Oh, by the way I forgot to add that when I had the decay vals maxed at 0 for 0-10mph I noticed with the scanner that the timing remained fixed at like 22*. Usually the car bounces around from 18-24 at idle. It was strange and also the idle didn't feel as smooth.
