secondary butterflies?

If you don't already run a PCIII or some other box, I wouldn't bother to remove them. Your O2 does not trim for fuel above 80% throttle opening.

How does a TRE unrestrict air flow ??? (T.R.E. Timing Retard Eliminator)

Hey BusaWizard... How have you been?

I'm fine Sir, thanks for asking, and yourself? Happy Holidays to you and your love ones.
