?'s about tuning, pinging, and Compression

Hard to not notice pinging. Kind of a tinny knock. Them aluminum heads are helping alot. I don't think them octane ratings are very accurate either. I go to one gas station in town and can run regular 87 octane and not ping. Fill up on other side of town ping on their super premium. My lawn mowers don't even like there gas. I've been reading alot of articles in mopar mag kicking out some serious horses on pump gas.
