Agree that pulling the resistor on a stock vehicle really makes no noticeable difference in performance. It does however make a difference on a turbo vehicle.

Pulling the resistor increases retard, right? Which I understand may reduce detonation under boost, but on a normally aspirated engine, it would actually cause a power LOSS instead of a power gain.
I'd still like to see factory documentation that shows 6° retard for a resistor value of 750 ohms (as well as for the other half-dozen values). The FSM (
