I have that on my CSi and it is very powerfull. I bought a used pressure sensor that had the hole drilled at the end and I made the adjustment to have the engine run at its smoothest. But once I put the original pressure sensor in (just for test purposes), the car idles rough and doesn't run well at all. I guess I have kind of enriched the system to handle the bigger engine. I have also increased the fuel pressure to about 2.6 . The other day on the freeway, I pushed a bit and the car effortlessly reached 100mph. It really works well.
