You will just have to start praying that VWs new performance R devision does what BMWs and FIAT/Alfas does and starts offer rechips for its cars. 
I am on my knees already!
Do you think this may ever happen? .....You tease.....
I do hope so.
Its a way of manufacturers to reduce CO2 average of there cars by offering off the shelf higher power versions as an accessory at there dealers rather than straight from the factory.
Its why BMW, FIAT, Alfa, Vauxhall(well it was actually the fiat TDI kit), MINI all do it.
It makes clever buisness sence.
So come on VW

get with the times. Its not like this is the first time you would have done it

(They did it in the 80s with the mk1 16V)
