I agree with the reply from Greg Roles above, the GT 125Kw has additional mods to turbo and fuel system and consequently have a different tuning profile. I have the Viezu (formally Chipped UK) ST3 with a Pipercross air filter and exhaust upgrade, it is excellent. I can change it back to VW standard anytime (like when it goes in for service etc.. (it plugs into the OBD port and re-programs the ECU) not just a gadget that plugs into the temp sensor to fool the system that cold air is available as some do.....
Volkswagen Golf performance exhausts and tuning products from Milltek Sport
There is quite a few to choose from, read the forums well and good luck

I have seen a few places offer a 103 to 125 kw chip and a 125 to 149 kw chip
Are these for the same motor?
What other mods do i need to enhance the upgraded chip? ie exhaust, air filter.....etc
Thanks Ash
