Opinions are divided on these... some specialists advocate their use, others do not. Personally I don't think they are of benefit on Trionic equipped cars, and may even cause some problems. The way I look at it is that Trionic is a clsoed loop fully adaptive system. This means that (within limits) you can alter any element and the rest of it should adjust- which is why it can cope with a fixed increse in fuel pressure. However, the FSE gives a continually varying increase in fuel pressure that will not track what is being reported by the MAP sensor and thus, I think, will make it difficult for fuelling to be accurate.
I used one on my LH/DI 9000 and it did seem to improve response. I also tried one on my Trionic 9000 and didn't notice any difference.
A few folk have reported that the pressure of FSE drifts over time and needs checking.
