:hit 12.5 or atleast mine does. I don't know about the 14 psi, do you have any Eprom upgrades or boost jets? : no,not a single upgrade besides those two. I installed the Jspec ecu with the jspec motor. I have the udsm one but I was told to use the jspec. On top of that after the test pipes I have the OEM H pipe and OEM mufflers( at the time I ran out of loot) other than that,thats it
