i'm running hks t04 hi fi turbo. I'm currently using the SBC-ID to control boost. i set my boost at 12psi, and the peak is at 14psi. lastnight we were doing some testing, the boost jump up to 21lb. does it mean my boost contorller is not working? or my wastgate didn't open? should the boost controller open the wastgate eventhough the spring on the wastages is from 22psi?

i'm running a 12psi spring on my car with the blitz sbc-id. it can keep the boost down to 8psi in lower gears!
make sure the solenoid is close the wastegate the further away it is mounted the worse control you will have!

i removed the vacum off the wastgate. i still see 16lb before i let off, since my wategate is only 10lb spring, is that mean the wategate never open? it should open when i boosted over 10psi right? is there a way to test the wastgate to see it's working propertly?

the blk box is mounted on the same side as the turbo, just below the strut bar. I don't remember reading anything on blitz site about longer hose? anyway, if i back out the screw on the wategate itself, it shouldn't boost more the my what spring rate is right? if it's still over boost which mean my wastegate is not working at all?

i really do not know about that blitz controller, but if it has a duty setting on the solenoid like my avc-r, that could be your problem. IF it has a duty setting, try setting it lower....??????
i am sure that this did not help you one bit....
