Let me start off by saying I have done quite a bit of research and have been unable to find exact answers for my questions. I'm fairly inexperienced.
I have a 05 c6 e40, 408 with a 235/243 621/624 115+2. I'm having issues with idle dip/stalling, going from higher rpm to idle (pressing clutch). I started by adding 19* to my base timing and coast down and base idle to 800. I know I need to adjust my base idle airflow but am unsure how to do it correctly. Any advice is greatly appreciated.
Thanks, Chris Wood
