Yeah, but it's on the verge of too high for premium. If i ran a more aggressive cam to bleed some more compression off i could get it safely within the pump gas range, but aggressive isn't what i'm after.

And i was figuring it probably wouldn't ping when over advanced, that's why I'm going to track tune it. get it setup to make the fastest runs, plus it'll let me try a step rich and lean on the jetting.
