Again, NA tuning is expensive, spent close to £1000 completely reconditioning the head, new cams, valves, seals etc
Few things you could to change the "feel" though
In the states the use MK4 12v VR6 head gasket as appose to the MK3 one, slight increase in gains and increased compression
Also a lightened flywheel will change how it will drive along with MK4 V5 gearbox.
