Wastegate spring and ECU chip should be your first step. Also K&N filter
if you haven't it done already. The problem is, Audi's auto transmission
cannot drive much more torque that comes from a stock engine. So you
shouldn't expect much power increase without burning the tranny.

If you make any performance mods involving increased boost pressure you
are more likely to have knock condition occuring in your engine.
Therefore, I would strongly recommend fixing the knock sensor before
doing any mods.

You could find a good used manual tranny on the junkyard and sell your
autobox, it could lower the cost significantly. The swap will also
require changing the throttle linkage, some mods to the cooling system
and electrics, installing new pedals, clutch MC... a lot of work. And
you still can't put too much power if you have only front wheels driven.
If you are heading for real performance, why not sell your car and get a
