Well, stuck the green filter in last night and have noticed a marked difference in sound, car seems louder and you can indeed hear the recirculating dumpvalve whooshing when you come off the accelerator. Sure the car is quicker too, although, it might be my imagination.
Car's going in for a service tomorrow and they're going to stick it on their rolling road for me. I had it done about 4 months ago and had 3x consistent readouts of 307-309bhp, wonder if i'll get any more, only thing that has been changed is the filter...
will report tomorrow.
