hmm.. it's probably been posted some where but too many post pop up when i search...plz link me if there's any... here's the deal, i have a greddy profec boost controller on a 3in tbe test pipe with a drop in, how much boost is safe? or should i just let the guys tuning/flash my car decide? Yeah i'm in sf bay area in cali, and debating on who to go to....

thanks guy

ps it's a IX not a VIII

 

so.. no one can help me?

 

Well, 21psi would be safe. But from what I've heard the 9s can boost a little more than the 8s because of better coolant passages and maybe some other things. Keep looking around and you'll see it referenced somewhere.

 

thnx.. anymore?

 

bumpy..?
