    Um supercharger wine?:D

    I would take a good look at your intercooler boots. The stock ones are the best. If you are going to replace the green gasket I highly recommend a Detroit tuned bypass valve. The stock ones are slow to close and Dont always close all the way. This causes you to lose boost. There is a chance this is your problem. Other than that just check all your hoses and vacuume lines.
    Here’s a link to Detroit Tuned.

    and if you really want to be certain intake leaks are resolved put one of these on the throttle body, soapy water, and any leak will be revealed. Should be standard issue with an R53 IMO.
