I really shouldn't stick my nose into the middle of this but I have to.

If you use Byrons, add an ounce of castor to every gallon. It needs it. No, not every driver or every engine is going to see problems without it but adding it prevents you from being one of the ones with a problem and hurts NOTHING. In fact, I find it to actually be a bit crisper and easier to tune.

Or just switch to Kosmic or something.
