Installed I have 250cc injectors. I have a Walbro 255 LPH Fuel Pump gas pump, and 250 inj. Turbo is a T3/T4 .57 A/R. With a Apexi NEO, AEM UGO gauge.

I would typically recommend 250 cc/min injectors for 125 hp max on forced induction for a four cylinder - that's way too small. 315 cc/min injectors would top out at 157 hp - not exactly a huge improvement. These may be slightly cautious numbers, but I'd go significantly bigger, maybe 440 cc/min or even larger.
