Hi,

Upon reading various forums and threads, I can't seem to get my head around the differences between the 122 / 140 / 150 versions of the 1.4 TFSI engine. Now, as far as remapping abilities go, the 122 and the 140 seem to be able to be pushed up to 170BHP whereas the 150 can be sent up to 200BHP with a revo map. Seeing as people are claiming the change in 2014 to the 150 from 140 was only for emmisions standards, why is the engine producing less power if it was only a software change?
