    Capa has a cp1 fuel pump which has a gear pump located behind it for feed pressure. Installing another in line pump is not required to be honest. Stock cp1 is good enough with rail pressure drop for around 800nm (385hp).

    I did find that the extra pump stopped the fuel rail pressure dropping as much as it does when hitting high 300bhp numbers. As you say you can work around it but I figured it was better to try and maintain the fuel rail pressure resulting in reduced injection duration and hopefully better atomisation .

    Thanks for all the help,
    Car is booked in for the 11th September with Rick so will give me chance to do a few bits and a service. My goal it 370-380 750nm if I hit those numbers I’m hoping I’m happy but obviously comes down to the way she feels, at them moment she’s meant to 300bhp and she’s ok. Since adding the turbo boot comes in later but pulls much stronger to redline. So hoping a the map can bring it back in earlier

    Hi Karl, massive thanks again, fuel pump install went smoothly which is nice. Found I can get to the MAP sensor easy by removing with wheel and going in that way, was easier than removing the head light. Car is in at Ricks in the morning, nervous but looking forward to it.
    Thanks again!

    Hi
    I watched a video on You Tube Darkside Developements A5 3.0 with a DSG 400 plus BHP and 600 NM and it developed a crack in the bell housing.
    Enjoying your Thread.
