Right now I have a thermal exhaust, greddy profec b spec2 ebc, greddy ebg, greddy bcc, and a apex'i s-afc2(untuned). My downpipe is not on yet but what should be my max boost with this setup? And to any Greddy Profec B spec2 owner what setup are you doing? And last......Does 1bar=14.5psi?

im not sure what you trying to ask, I have a high-flow cat and i saw this post, i have no problem boosting to 1.7 bar (did it by acciddent once) with the high flow cat. i guess on stock twins you could boost to 18 psi with a cat on the car or whatever. i really dont know sorry if i didn't help.

dont boost more than 18psi anything more than that and your killing your turbos in the long run.

If you can't boost past 1 bar it is probably the cats that are holding you back. They are very restrictive and will not allow the turbos to "breath". Just throw the DP on and turn the boost to 18psi. :)

Then I guess im boosting only 11 or 12 psi because I just can't seem to reach the 1st bar. Anyone know the Greddy ProfecB spec2 in and out that can help out a brother with it? Its my 3rd day playing with it.

dusty, with a single turbo can you boost past 14 psi on stock cats?
