Hmm...just wondering would any kind of tuning be beneficial? (i don't know hwo to read the curves properly haha)

sounds about right for a stock motor mate. altho, seems to be lean at the end. im not a tuner, but reports of 130-140kw atw are about regular.

Lean it out some more, i'd even try a whole a/f point to see what effect it has to torque.
Your actually in a good position (because your a/f is flat enough) to be able to shift the whole curve uniformly to determine the impact to torque.
Give it timing between 4-6k rpm

1st run is blue, 2nd is red.
Power & fuel curve looks stock. Do you have aftermarket ECU?

no everything is stock, its a 99 model and it had 63000kms at that time...what benefits will advanced timing do?

No can do... Timing is fixed through ECU. - non adjustable magnetic pick-ups.
To change timing, you need to address the ECU.
You can adjust fuel pressure which will affect the total fuel delivery.
Again, std parts are no good.
If the car is bone stock, you'll get bugger all gains tuning it anyway.
If you're wondering why it runs rich flatout in std trim,
It's so it doesn't blow up within the warranty period.
