is there anything i can do on my A2 1.4L petrol engine to improve its performances and response? i heard from an insider that AUDI was not going to launch the LE MANS V10 twin turbo because it would be in competition with Lamborghini, wich is as we know part of Audi Group. any information?

This German tuner offers a chip that hikes the output to 90 bhp:

And there's something called 'Power-system':

Other than that you could take the rear seats out and shave a few kg's off your own weight. Also, a full stainless steel exhaust might help.

P.S. I don't think the V10 would even fit into the A2 :D
