disconnect the vacuum line that runs from wherever to the wastegate. i imagine you are using a delta gate and only have the side port hooked up. so somewhere in the middle of that line, cut it, install the boost controller {grainger regulator} and go nuts. remember to set the boost controller all the way down {zero bleed} should be all the way clockwise. {dont quote me on that} when you put it in look for the words in and out on the controller....might have it might not. in will go to the manifold out to the wastegate.

its not rocket science. one full turn of the controller should yield a pound or two of boost.

I understand that the closer you put a MBC to the wastegate, the less likely you are to spike. being closer to MBC the wastegate will get the boost signal more quickly when the MBC opens up, so the turbo will not keep spooling past whatever the target of the MBC is...

This is what I was looking for if any one is intrested. My turbo has an internat wastegate, and with this setup I will be able to adjust boost very easily.
