I will be in the long run, getting a professionaly setup supercharger on mine

Unfortunately, which will be mentioned a few times, it's expensive. Money you spend doing this could be spent elsewhere on another car with better performance figures!
This will also get mentioned, quickest and easiest way to up the power is to follow in LLs footsteps....1.8T conversion!
With all that said i would do a lot of research before hand to find out what the best road to go down is.
SUPERCHARGER FTW!!
