    Hi all, my a4 has recently started to suffer from turbo surging, my boost gauge is bouncing from 1bar to 1.5bar and the car does not feel happy.

    I have a forge splitter in recirculating mode, and am wondering if it has now settled in and perhaps the spring needs adjusting, from my sympton should i go softer or firmer with the spring?

    Cheers guys
