How do I run wastegate pressure only?

What is the correct way to route the vaccum hoses to run on only wastegate pressure?
I know to run a hose from the turbo outlet nipple directly to the wastegate actuator and bypass the MBC altogether.
What do I do with the hoses at the MBC, just cap them off?

Yes, that's correct. Just run a short length of hose directly between the nipple on the compressor outlet and the nipple on the wastegate actuator. 1/4" hose should be the right diameter.
If you have an MBC, I would just remove it from the car. But, if for some reason you can't, then, yes, capping off the nipples is probably a good idea. Most MBCs have 1/4" fittings on them, so you'd need 1/4" vacuum caps.
If you're running stock boost control, remove the hoses that lead all the way to the stock boost control solenoid and cap off both side fittings on the solenoid (one will use a 1/4" cap and the other a 3/16" cap).

8.9psi is equal to about .061 mpa i think so the .06 is right on. but .08 is over 11 psi so i dont think you should be seeing so much.... but then again i'm not too educated on how the bcs works really...
