There was a lot involved in eliminating the surge. The basics included getting the fuel trims sorted first. The idle speed and min airflow tables were addressed next.
The Over/Under speed timing correction tables were also key to getting it dialed in. Timothy is welcome to share the tune file if he'd like. I'll leave it to him.

Thanks,
