Spoke to the salesman at the local Audi dealership about the 200 HP of the new A6 vs 190 HP of my '98 A4 2.8 - he reckons that Audi(USA) now authorizes a certain chip that will bring up the HP on the A4 to about 205-210 HP - this being without voiding any warranties etc. He is still trying to get the details thereof - any listers with any more info on this??
