audi ecu part number...replacement???
Hi all, i am new to the forum and new to audi. I just bought a 2001 audi a6 2.7T. The guy said it has new waste gates, stainless exhaust from turbos back, and racing suspension...which i believe because it is visible. But he also said that there was a racing ecu in it. there was a box in the trunk with a ecu in it. it has a part # Bosch 4B0-997-551-AA. The box has part # 4B0-997-551-DX which is supposed to be in the car now. I was wondering if this is an upgrade ECU or just a replacement bc the only difference is the DX. He also said it was pulling 398 hp on the dyno...is this poss with just these upgrades??? thanks for your help...MATT
