that is what I am thinking too. I consider myself a newbie to ignition tuning.. it's my first time doing it ever!

From Nate's table, I do believe the degree in advance is alot! But I don't have a general idea of what alot is considered as ALOT!

So you saying, the higher the octane I use, the higher degree # I can use in the table?

so thats' why since I am running octane 93 instead of 100 (compare to Matt's table) so that's why I should substract 2-3 degree from his table above 100kPa?

Thanks for the heads up!
