i wouldnt why do you wonna do that now it's winter i would turn it down if anything mate.

i run 17 psi but ive got a pace intercooler,ss exhaust,piper x air filter and a 1700 bottom end, ive also had it chipped.

on a standard engine most peaple wouldnt go anymore than 10 - 13 psi the most.

if you do go ahead and do this make sure you get it set up.
