I have a Brand New A3 2.0T and after 1500 miles i took it to Revo for Ecu remap. For a month or so it was great but then it felt sluggish for some reason, i took it to Revo man who said that the car had set itself to a lower boost setting. He tried to set it back to standard and then reflash it again to the higher setting, but the car set itself to a lower setting again....I called audi who couldn't see the revo and couldn't find any fault codes or power loss....Revo man said it might be a faulty diverter valve??

Any ideas?....Don't like this standard 200bhp driving much...please help!!
