I'd have to vote for none of the above. My power upgrades were new plugs, a recent oil change, and an induction service a couple of months ago. Oops I forgot, I checked my tire pressures. Those things will help restore power you likely have lost over time. Those who think they are hurting on power need only come up here at 6000 feet of elevation to see what you're really missing.
