adjusting a stock wastegate?

[Daytona_83]

I have a 1977 Dodge D100 pickup with a slant six that Im using a GN turbo on. I have read that the engines in stock form can handle 10psi daily driven, but I have heard that the stock wastegates are rated at 14-15psi. Is there a way to mod the wastegate actuator to run 10psi?

Is your actuator adjustable? Does it have threads on the rod?

I actually dont have an actuator yet. Im looking to buy one (I put an ad in the wanted section). I saw adjustable wastegates but the smallest psi setting I heard they go to was 12. Can you mod them to run 10?
