boost controller
I think i'm a going to but a subaru legacy turbo. But the guy said it is set up for 12Psi.....can i use a boost controller to set it instead of changing the waste gate? I only want to run 5-7psi

Re:boost controller
why would you want to lower it? if that's the factory setting, then that's what it is meant to run 
but if you must, no you can't LOWER boost with a boost controller, you can only raise it, so you could either get a new wastegate, or make the actuator arm longer to lower the boost then you'll be able to adjust it with a bc, just not lower than what the actual wastegate is set at.

Re:boost controller
I think they thought you were buying the car not the turbo for a setup..
You cannot lower boost with a boost controller, you can only raise it.
You will have to alter the actuator's shaft going to the wastegate in order to lower the boost.

Re:boost controller
just take a rubber mallet to it. Bend the actuator down/in to lower the pre-set psi. Works just like lengthening the arm, just easier. Do it the really ghetto HMT way.

Re:boost controller
yeah, i thought you were talking about buying the car and lowering the stock boost :P anyways, just cut the actuator arm and weld in a piece of metal to make it longer, this will lower the boost.
im not really familiar of the legacy turbo but i imagine it might be more powerful than the dsm turbo and i've been told that the older gen dsm turbos dont last long. If it was me i go with the subaru turbo.
