I went through a complete rework of the 02 OS and 00 tune and the results are good but I have this annoying idle hang for a few seconds after I come to a stop which I suspect is also making it slow to decelerate. If I change the TC and TF airflow and or decay it's better but still hangs when I come to a stop and slow to decelerate. It hangs by about 100 rpms. I didn't have it when I was running the 02 settings so I just think I'm missing something. I went through the idle tutorial but don't see anyhting that causes this? Thoughts?
