Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

Gap is 35, same plugs as came stock and what dodge recommends.

I usually do yeah, when I don’t I have dieseling issues but the booster works well enough. The current tank has no booster however, 87 octane.

If you have a look at the pic of the plug see how its consistent all the way through out from the strap all the way down to the porcelain. That tells you the mixture is well vaporized. That's a great plug read if the fuel doesn't contain octane booster
