Default Boost control issues

Curious if you guys have any suggestions...

i have a 13 Club with a 2.5 and a Fab9 turbo kit (EFR 6758). With the custom intake manifold and 3 exhaust Im making 360rwhp at 18psi.

Car was running great but the fuel pump was going out. Started running lean at cruise. The car was tuned to run 16-18psi, max. The line one from the boost control solenoid came off- zero boost control and saw psi over 20. I attached it with a worm clamp- then only 7-9psi (spring pressure I suppose). Took it back off and 20+ again. I replaced the solenoid, so doubtful both are bad. Is this a wastegate issue? A boost controller issue Im using a SGC1). Something else?

Why are you going into boost with a bad fuel pump?

Possible the reason i cracked a piston in half.
I bought a bigger fuel pump the next day.
Learn from others mistakes.
