    Ideally get a set of red injectors, You can keep your original fpr (3bar) and fuel pump if not the fpr should be 4.5 bar which should have come with the phase kit and a bosch 909 fuel pump.

    Also invest in an air/fuel ratio gauge that takes a "live" lamda reading, Ive just got one cos I suspect my car leans out at high revs, only 52 inc

    was it a drop in fuel pressure causing the underfueliing if so what was the fuel pressure and at what revs did it drop

    Assuming you have fitted all the phase 3.5 bits, just make sure your injectors are clean and performing well, and ensure you have a high enough voltage going to the fuel pump.
