    Hi, I am after a forge or DV30 for 1.8T can anyone help? When under boost gauge is fluctuating up and down between 0.9 and 1.1 bar is the std dump valve the problem?. Had evo fq400 valve on but wouldnt open off throttle(too strong I think) put std valve on and have had this problem since.
    Thanks for your time.

    Forge would be a good place to start.
    lots on eBay
    Would check all pipes and connectors, OEM DV's have a habit of the membrane splitting leading to boost pressure loss.
