    How critical is gallon per minute number?
    I mean if say plugs look best at 17 gpm how much can you very and not notice difference in time slip.

    16.5 verses 17.5??

    Main jet changes of 5 numbers is in range of .1gpm
    Does .1gpm make any difference?

    If your engine is already rich, being a little richer or a little leaner makes little difference.

    If its tuned to the max, then yes, being a little too rich drops power and a little too lean hurts parts.
