Correct A:F Ratio @ WOT?

[Bruce]

You never,
ever,
tune to an AFR.
You tune for performance and note trends, or validate corrections made with
a WB.   In tuning you let the engine tell you what it wants, you never try
to force it to run where you **THINK** it should be.
A WB is just one more tool in your box, it, in and of it's self is nothing.
