RS tuner from Fastchip

So i've read a bit about this on another forum and asked the Guy what I can expect to achieve with it.

Has anyone got one, with the map etc ? What sort of differences can I expect?

I'm not too bothered about bhp, just a bit more torque lower down would be nice. And if fuel consumption is improved then bonus!! :thumbup::thumbup:

All in all - Is it worth it?
