Hey was wondering what the cheapest and best option for remapping ecu on 2008 golf gt sport tdi??

I was wondering if anyone can provide info on getting my 2003 T4 2.5 TDI remapped in Melbourne?
The UK forums seem to have plenty of info but I'm not finding many options in Australia.
It appears that up to 50% increases in HP and torque are possible after fitting Bosch .216 injector nozzles...

Hi All,
As the title says, I really want to know if anyone has tuned a VW Golf MK4, 1.6L??

I know it's not the best place to start, but I love the colour, it's unique, and have the suspension and wheels siting almost right (for a daily).

I just want a bit more oomph trying...
