i have a b5 a4...the car rus good but the turbo doesn't kick in the way it should and it don't pull the way it should.

have you checked the turbo for any shaft play play? do u have a boost gauge? problem most likly is that the turbine is worn down from shaft play and its not pulling like it does cause i experienced this 2months ago with my oem turbo with 136k on it take it out shaft play like hell rebuilt it with messed up turbine wheels and didnt pull like it use so i just bought a centerpiece turbo cartridge and installed that almost 2k miles on it and its still pulln hard 10ibs of boost:) non tuned stock a4 1.8t with 2 1/2 in custom exhaust with test pipe drop in filter and mbc :)
