I just bought a 98 A4 Quattro with the 2.8 and Tiptronic tranny. I am having the engine rebuilt most likely with a S/C. The power from the new engine might be as high as 350 HP. I'm having new internals put in and head work along with a chip and the S/C. Does anyone know the power handling capability or any upgrades for the Tiptronic? Any and all help is helpfull.
