what should my 1j be boosting at?

[jzxseven]

Hey everyone, I have a 1J in my Cressida and from the reading on the boost gauge it reads about 11 - 12 psi, when I boost. I have the boost gauge hooked up to the port closest to the firewall on the intake plenum. I was told it should be boosting at 14 - 15 psi with the mods I have. Any suggestions?

mods are:
FMIC
Hard pipes
Greddy BOV right before throttle body, also stock BOV is still hooked up
after market y pipe
3" down pipe
3" piping all the way back with no cat to a 3" Flowmaster Super 40
2JZ ecu
PLX Wideband set up
