It is checked during a dyno run and costs an additional 10-20 bucks on top of a basic dyno run. The A/F ratio is best when it is around 12.5:1 to 13.5:1 from what I have been told. Abit on the leaner side is said to be better. I'm new to this and have just asked this same question on another board. Hope this helps.
