No reason not to, there are thousands of TFSi engines running around if Golfs' Leons' and Octavia that have been mapped without too many issues.
A word of warning, do your research and don't be tempted to buy too cheap. There are a couple of companies that have the TFSi market well sorted based on a wealth of experiance in the US.
Also you have Superchips Bluefin which is on special offer at £390 until the end of Jan - Excellent value.
A remap will totally transform the car I promise you.
