2001 Saab 9-3 Turbo Upgrade Help

Hello there people. I am driving a Turbo 2001 9-3 currently and am thinking about keeping it. I am impressed with its performance but would like more. I was wondering if anybody can help me with the beginners modifications or upgrades to apply to the car? Thanks!

We have a large car club with turbo as their speciality. Most of the forum is in Swedish of course but one general section is for English writers.

I have a feeling that they will recommend to change chip as one of the easiest things to start with.
