Rather than clog up other people's threads with this I thought I'd create a new one.
I fiitted a RS4 fuel pressure valve to my S3 Revo stage 2+ today, I used a how to from another forum which was pretty much spot on and made the job much easier than I expected.
It took me 1.5 hours but dependant on your ability and tools may take 2 hours or so.
I was unsure whether I'd notice any difference fitting this valve as I didn't have any issues before, yes there is an improvement with this fitted in that the car is more progressive now.
Before when pushing on the boost would come in but after 4000 rpm would come in very hard and aggressive. Now the boost still pulls as hard if not harder but is a constant pull from start to finish.
That's the best way I can think how to describe it.
As for fitting I only had a 14mm crows foot and couldn't find my 17mm!! But I managed.
My valve didn't spin out with my fingers once slackened so I used long nose pliers to turn it until removed.
The hardest part was trying to enter the new valve back in with limited access, I managed one hand from the top and the other from underneath.
Definitely a DIY with no bent scanners required.
Here's the "how to" I used and hopefully it will help others
