I know how both wastegate works. I see what you mean tho. By taking the internal wastegate flapper off and routing that area to an external wastegate.... daym, that is too much of an inconvenince trying to rig something like that.....

I'll give a brief run down of some basic wastegate information.
The "gold can" often associated with the internal wastegate setup is what's called the wastegate actuator. There is a spring in there which determines when the actuator will move the arm and open the wastegate. From your info, this spring is a 12psi spring. You change the spring, or to an actuator with a different spring, you change when the wastegate opens.
Did you understand taht last sentence?, because that's your answer.
If a dumbass tells you that you can turn it down with a boost controller, kick them in the nuts and never listen to anything they have to say ever again.
You can always run an external wastegate and solve everything, the downside being more money and more work.

Since I already know the arm is not threaded I didn't bother. Pats actuator arm is like that, I know plenty about it you're not telling me anything new.
Thanks and don't let the door hit you on your way out of this thread.

heat...you crack me up 
well the way i figure, ill just build the car for 12psi, im not gonna half ass this. there are decent budget parts i can put in to handle that pressure.
