Help with boost controller

Hi guys, I’ve got a SBC I-D blitz boost controller, I’m also running a g-tech 2 chip. I can’t seem to boost over 1-bar and with the g-tech 2 I should be achieving 1.2bar.

I can’t for the life of me figure out the boost controller and no amount of YouTube videos have helped me.

Can anyone shed some light please?

Many thanks Steven

My first response would be is the wastegate actuator not worn out?? if its the original 0.8 bar actuator then it may just need replacement with a 1.0 bar variant
