    S3 8L Remap stage 1... Possible air/boost leak..?

    Hi all,

    I Just had a remap stage 1 to my standard S3 8L 225 taking it to c. 255b and 360n..makes the car a real pleasure to drive.. I was cruising in 3rd and 4th gear today at about 2200revs and when I put the gas down to accelerate there was a slight shhhhh sound that I've never heard before, which occurred between 2600 and 4000revs, and what seemed to be like a slight loss in boost/power.. Can anyone advise the cause and fix to this? Slight air leak possibly?..

    Thanks
    D

    Yes, so have a look for the leak, check all the boost pipes and clips. Smoke test will help hugely

    Thanks Superkarl,

    I'll check for leaks tonight. Bit of a novice question but how do you get a smoke test?...

    Thanks, I checked it last night and everything seems fine.. Going to take it into ZenSport later in the week to get a professional opinion form the guy who did my remap.. [maybe it's just the normal noise of the turbo etc that I've not been aware of before]

    Also, have got a Forge 008 diverter valve on the way as read these are a must upgrade after stage 1 as the stock DV doesn't hold the boost that well.. Is yellow spring the correct one to use?
