Quoted from the other thread you have going:

Open should take the car down to wastegate pressure (11PSI).

Closed should take you as tight as the spring inside the MBC will hold.

No need to create another thread.

Open the MBC all the way up!

I have figured it out , the pros that installed my MBC, were still connecting the selenoid to the equation. So im guessing thats why it tapers, because the ECU is still telling to taper at high rpms.
So I have to disconnect the selenoid two, and plug the 2 holes, but what do I plug them with?

and 'T' the BOV line, and thats when my boost will hold to redline.

Taking selenoid out is the way, but is it safer, will more constant boost mess something up?

thanks for all of your replys, even the bad ones..but hey we are here to learn right

Thanks EvoM.

You can buy 3.96mm vacuum caps at pepboys to cap off the stock solenoid.
You need to keep the stock solenoid plugged in.
