I have noticed since changing my plugs from NGK PFR6Q double platinum to BKR8EIX Iridium on Saturday that the car drive so much smoother and the delivery of boost is much more controlled.
But more importantly i used to see the boost peak at about 20psi and drop off to 15, Now i have changed the plugs it peaks at 22psi and holds at 19.

Can this be possible just by changing plug? :stupid:

The more boost your seeing is gonna be the colder weather we are seeing.
