as above for WRX95. Will 200 liters per our fuel pump work fine for the car. Mods are decat and boost controller (though dont raise it more than 1.0 bar) if it make any difference.

Pumps are rated in "flow v pressure". So you need to check at what pressure the pump can flow 200lt ph.
As stock, our cars run 3bar fuel pressure @ atmospheric, you then need to add the max boost pressure to this, EG 1bar boost gives 4bar fuel pressure. It's a good idea to allow some "head room", so check the pumps flow at 4.5>5bar.
