Awesome thanks man. Regarding plugs, how come so many guys ru nP3 and P4 then, dont they worry about losing top end? Question is how minimal is the loss in top end? The Keep 7 is a top end motor so to speak so prob not that noticeable? Maybe Ill run a P4 instead of the 3. I didnt like the Nova c6 that everyone suggests, didnt run strong enough or consistent enough.
