Laurent from Greece

I bought my a3 5 months ago and feel that the car can cope with a lot more power/torque, but how do i start?
1. I think first comes the ecu upgrade. I have contacted abt & oettinger and offer +45hp, there are other companies but i prefer to trust famous companies even if paying double, any sugestions?

2. The air filter i think is also safe and cheap.

3. what is all this about increasing the turbo pressure, can it be done safelly by a dealer? does changing the ecu actually increases the turbo pressure anyway?

4. exhaust pipe. is it worth upgrading to something like the one that the s3 has?

5. larger tyres from 15 to 16 or 17?

6. anything else???

thank you,

laurent
