Timing and afr

This cars timing was set as 60. And the afr was at 14.5. Was that a nitrous tune? What is stock timing and afr?

I don't think so. How do you know? No! It is not just one value.

Typical nitrous timing while on the spray on a vette is ballpark 15 to 25 depending on the size of the shot.

AFR on nitrous should be 11.5 to avoid turning the big pieces into little pieces.

This tuner on the car has value bars and that is what they are set to. I guess they may be limits but that is the setting. This car burns oil and only has 91k so I imagine that the rings are burnt due to nitro
