    Urs6 not performing!?

    Just recently my s6 has been under performing drastically, there is little or no boost especially at low revs the fuel consumption has dropped to 17mpg on a run and13-15mpg around town, i have checked hoses for leaks but cant find anything, a friend has suggested that it might be the maf? any ideas please im stumped.

              or a lot other things....
              what boost do you get?
              what about DV, n75,....
              any hesitation under hard acceleration?

              first thing to check as mentioned: boost leaks, then connect to vag-com, cleaning maf......
