Read my plugs, was carbon fouling on 93 pump gas but not on 96 vp?

Not on US pump gas. You do that and it will kill power. Every single time.

Even on race fuel I don’t get color like that, even though you are going to quote Shrinker (out of context) to try and prove your point.

No one I know puts that kind of color on a plug. No one. They must all be idiots.
Any fuel will do it. Shrinker was running 21 to 1 comp on pump gas and correlated burn conditions to plug reads.

Who do you know that was doing that? Exactly....nobody..

The reason you claim I miss quote him is simply because you can't understand why he says what he says.

Imagine running 240 psi cylinder pressure on 87 octane fuel.
