Found a TurboXS MBC for $45.
I'm wanting to turn the boost in my turbo'ed outback up from stock 8 psi to 10 or 11. What do you think?

Of course, thats a good piece to have.

MIght want to check your duty cycle on the injectors, but I seriously doubt you will come close to maxing them out.

switch to the walbro, not that you need it now, but its easy and for the future.

Remember to get a good boost gauge so you know you're setting up the MBC correctly (and start boosting it low and slow).

The EJ22T ECU will cut fuel at 12psi correct? I was going to just turn the boost up to around 10psi after using a wideband o2 to make sure my AFR's were safe enough. Thanks for the input guys.
