If your interested get a copy of VAG Com you can get leads from Gendan for less than £30 and a shareware version of Vag Com from Ross Tech, you can then run fault code checks and clear any errors, also you can run data logging too, so you can check N75 duty cycles and MAF Values etc,
As has been said get a turbo back exhuast, a panel filter and a front mount and with a stage 2 map you will see 230 - 240 bhp out of your Ko3s turbo,
Theres a guy on here Furry who runs a VRS as his track car
