Default Boost maxed out at 9.8psi

So I've fitted a shanghai windmill on the car with a hose of other performance mods and was hoping I could wind my boost up to around 22psi.
I'm running a Innovate SCG-1 Boost controller/afr gauge and no matter what I try to do settings wise my boost seems to max out a 9.8psi.
I have a ported internal wastegate if that matters.
Can anyone shed some advice, could it be my turbo or is it more than likely the controller I'm using?
Not sure where to start.
Thanks for any input.
