I finally had the courage today to drop down pulley sizes from a 3.6 to a 3.4 on my GTP which currently has an Overkill Tune, Autolite 104, Plog, 3" Downpipe, U Bend Delete, Magnaflow Catback, 180* T-Stat and KN CAI.
I was seeing 3* of KR at only 40% boost, should I go back to a 3.6 pulley for now or is this an acceptable limit?
