fuel injector question

We are about a 27.8# if I remember correctly so those would probably do well for a turbo car.

They drop right in and use the same connector. We have a 4 bar (58 psi) returnless fuel system. They flow 41.7 lb/hr @ 4 bar. However, I have noticed some irregularities which I partially attribute to fuel pressure not being measured directly by the ECM. Since the system is only regulated at the self-contained pump, the ECM assumes 58 psi at the fuel rail and uses the MAP sensor to find the actual pressure drop seen by the injector (engine vacuum increases flow). I have some work planned that will systematically get me to the bottom of the irregularity over the next 2 months. What year GXP? What tuning software will you be using?

Here is my thread on the irregularity I was referring to:

The original injectors are going back in the car temporarily for a more careful analysis of the issue, but that won't be for a while yet.
