Below shows what I have seen in my car (here at 4700ft).
Stock Pulley 13-14 lbs of boost
Code 3 15 lbs
181 17 lbs
Code 3 & 181 19-20 lbs
Thanks for that, its really helpful to see the gains you got. I was reading earliar in this thread that someone thought having both a SC pulley and crank doesnt do much for performance but i see in your case it has. Im really wary about getting a tune, theres next to no srt6 in australia. Maybe a merc workshop? With an Intake and 181 pulley is it imperative that i get a tune?
