: Boost limits? How hard can I Push it?

Many of u have stated to be wary around 30-32 psi on a stock turbo and some of u have accidentally pushed the stocker to 45+psi (i have no desire to test my head seal that bad though! nor do i want my turbo scattered everyware.). I do have a blow-off on mine though too, so that should eleminate the Surge/bark seen without one. Since it was installed, i have never encountered surge at any time or before for that matter but i do want to push the boost up more. I was thinking of buying a Perrin BC from my friend off his STI. Not sure if it will work though cause my BOV uses the wastegate boost line a source to the spool valve as a psi differential to activate the BOV. I soppose i can make another boost source for it. Give me some feed back, i'd like some opinions! Thanks.

Also don't want overboost codes when i step on it every time. Has a BullyDog PMT
