30FE: Turbocharger boost pressure HELP!

Hey guys, I've installed the JB2 pin-out yesterday everything worked fine, I went for a test cruise, while switching between 3d and 4th gear at 4k-5k RPM, i get the half engine light with " Engine fault, reduced power " again and again, i got scanned many times on the GT1 and i got:

Please help guys it took me a while to ship the jb2 from the US, I'm far away from there, or else I would get the Jb3... any help would be much appreciated...

You need to turn the settings down. I am pretty sure it means more boost than expected. I had 30FF(i think it was) tonight and its because my chargepipe had blown off the lower charge pipe at 17psi and a janky tbolt connection because I didn't tighten it very much.

Interesting, normally you get 30FF. Undo the solenoid bypass then.
