[Wattsym12]

Got a 96 import Wrx been stripped and stiffened for trackday only use and feel it's time to upgrade got a td05 walbro 255 fuel pump was going to buy 440cc injectors do i need uprated fpr? Already got a reprogrammable ecu was going to stay with a wrx intercooler not looking for mega power just an upgrade but still reliable any thing else i should think about? I'm in Tunbridge wells can anyone suggest somewhere good but not 100s of miles to get a remap thanks alot
