    s3 issues help

    hi there bought my s3 about a month ago,
    and i have been have what i think are boost issues,
    i cant find any splits on any pipes,
    i have tried 3 different air mass sensors,

    if you are drivin normally it feels fine, but then when you boot it intially takes off but then feels to jus go flat until i ease off then feather the throttle ,

    any one have any ideas?

    many thanks ben

    Have you looked at the turbo to charge pipe? if there is greasy oil on the orange pipe? they can work loose
