I have a B5 platform FWD A4 with the AEB motor which has been chipped to run 12psi. Now through poking about I have found the AJL motor as found in the B5 A4 4x4 T-Sport is identical in every way shap and from bar running 12psi from the factory. There is also the K03s turbo but from speaking with people in the Audi club many 4x4 cars have been found to have a stock K03 instead.

Sooo. Could I perhaps get a chip for an AJL car and run that to give me about a 15psi and a bit more go?
