Cajunboy - please read this "sticky" in the FAQs for Gryphon programmers:

The "zero" values are all "baseline" settings that represent what Bill has programmed for your tune. Please pay particular attention to what is said about "placeholder" values for Tire Size (TS) and Gear Ratio (GR).
A +1.5 setting on the timing would be appropriate for an octane increase of 3 points over what has been set up in your current tune.
