This mod is more or less documented on how to do it without spending any money.

I don't see any HARM in grooving the throttle body or for that matter the heads of the engine.

And I do know some manufacturers have put in their own grooves for one reason or another.

I would estimate that this would have some affect on fuel atomization but I doubt it would be enough to effect FE to the point that we can remove variability.

But if someone here wants to be a guinny pig Why not?
