Ronotech is back...who are they? they left?

The company once established itself as a tuner of Volkswagen and Audi products, now seems to be focusing mainly on Audi's TFSI direct fuel injection and TDI diesel motors. Ronotech currently assembles "powerboxs" called R-Tronic, and according to Ronotech, it delivers 20 to 30 percent performance improvement in most Audis.

Not bad, but we'll wait until one shows up on our doorstep before we're truly impressed.
