YouTube video of the CEPA 2.5TFSI getting more efficient


A3 SportBack 2TFSI quattro DSG
Hi guys.
Some years ago (maybe 7 years) there was a YouTube video of an Italian motor company doing som secrets/tricks to the CEPA 2.5TFSI engine making it more efficient and gaining a huge amount of extra power.

I am not saying it was true. But it was a very cool clip.
I can't find it now and was hoping someone here would have a link to it...

Cheers and have a great and safe weekend.
