Default 15 PSI on a GT2554R?

I've searched and I can't really find many people who have done it. I just bought a Megasquirt (finally) and some 460cc injectors. I want to turn up the boost from 10 PSI to 15 PSI, anyone see any problems? I'm hoping for ~230whp.

A SR20 T25 is basically a journal bearing 2554. I have run mine at 15 psi. Do it. You should see an easy 230whp by 14 psi.

You didn't just buy a MS. You bought a MS3x of DEATH and FURY!

It is doable but you will be at the very upper end of the efficiency range of the turbo. Just watch the injector duty cycle and you should be alright.

I've heard of wiring the wastegate open, but in your case I think you're going to need to wire it shut.

Or else pull the signal line for the actuator?

Run 15. Start saving up for bigger turbo. Boost is addicting

Yes.
But then you have a 1.6, so you're pretty much one of "those" guys.

Just go buy a 1.8t turbo and have your diesel powerband

If I was to turbo my DD I would put on the exact same setup that I used to have. The one that you loved with that amazing 2554.

I'm gonna focus on getting it to run on MS first, this is gonna be a learning experience

Then I'm gonna try to get the 2-step/flat foot to work.

Thanks again Brain, I can't wait for the MS3x to arrive.
