has anyone tried Vito's power pistons or the high compression gasket kit? What kind of power does it give you, is it worth it, where does the power come on at? top end? mid? low? any info is appreciated

I just bought a set of vito's superstock pistons, but i haven't put them in yet. If you look at www.mobildyno.com it will tell you about its performance on dyno charts. I'll tell you how mine works out in a couple weeks.
