Question Can a Profec B control the boost in twin non-seq turbos?

I have non-sequential turbos, can I keep the boost under 10 or 5 psi with a Profec B?

Doubtful, but its not the profec's fault. I think the factory wastegate will always allow 7 psi (if its working properly)....more when boost creep starts.

Do you think that my wastegate is bad? maybe.
Could be because there is no difference before the Profec B and after the Profec B, the boost behavior is the same.

How could I check my wastegate or actuator?
