ive presently got a mk6 tdi golf running a plug in tuning box from the UK - it does the trick but i was hoping to go something more permanent for the Passat...

has anyone remapped their TDI Passat and can make recommendations of a decent diesel tuner in Melbourne?

plug in unit is around $500 for the Passat upgrades to 160kW & 450nM... was hoping a tuner could extract 180kw & 500nm
