standard gap on the focus rs plugs i had was 1.2 zetec plugs r 1.0 the gap ive found to work best is 0.7 on the focus rs plugs on my setup part of my problem was the actuator was wound most of the way in so way to much boost so ive wound it pretty much all the way out so theres basically no boost but it drives like a non turbo'd car so wen i get a boost gauge tomoroo ill set it up to about 5-6 psi until i get my emerald ecu fitted next week an get it all setup an mapped properly
