Boost controller help - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

If anyone could help me out that would be great. I am looking to fit a manual boost controller to my car. The turbo has an adjustable internal waste gate and currently I experience some creep that i am uncomfortable with. So I will be getting the turbo ported I guess and I was looking into some other ways to prevent the creep and control the boost better.

So I was looking at this boost controller
http://www.turbosmartdirect.com/Prod...Tee-Black.html

So for installing it on a car with an adjustable Internal W/G. Would I just adjust my W/G All the way as low as possible and use the boost controller to set my target boost? Most turbos I have worked with before(S15 SR20 turbo for example) where it had a fixed rod and I would just Run the boost controller in line and set boost with that.

I am sorry if im not very clear with my question but any help would be appreciated.

I would set your wastegate at whatever it's default is that way you have a known baseline to know where your adjusting from with the MBC.

Thanks I over thought the whole thing. I'm going to readjust my wastegate so that it has some preload and then install the boost controller.

You can not go under the wg spring pressure. If you minimal boost is set at 5psi you wont be able to go lower than that.

If your wg is adjustable I would go with the lowest wg spring pressure thats possible.
