[QUOTE="James, post: 117895, member: 2"] Pro Circuit claims that their high compression piston is designed to run on pump gas. However I'm not sure if they're referring to only the 13.8:1 or both. Might have to email them on that. Still curious on the low end power gains, is going from 13.5:1 to 13.8:1 really even that much? [/QUOTE]
