It seems that the WG goes bad with age, and mileage. I have about 100k on my motor, so yeah.
Also the benefit of the Hks WG is that it's adjustable, so you can set it up to 14psi.
But you should have it around 11psi, safe.

It's an actuator, not a wastegate. The HKS ones are quite nice.

When you are overboosting, do you feel compressor surge, or get launched back in your seat surprisingly hard (or both)? I had this happen when I was first dialling in my boost controller back in the day- legit overboost- scared me.
I don't think a screamer pipe would cause this; and like cotbu said, your exhaust setup is nothing that will cause an overboost situation. If the wastegate flaps freely with the arm disconnected; and it opens when connected with 7-8psi applied to the actuator, I'd wager you are suffering from an indication problem (bad gauge).
