APR bi-pipe and Apr ecu. I wsa just looking around in the engine bay and decided to check that the TBB was secured tightly and dint have any leaks or anything. So I pulled up the frist cover and noticed that there was no tbb. I thought it was strange and thought that maybe audi changed them for the '02 model year. I was wrong. I looked closer down on the pipe and behold, there was an apr logo. This got me thinking, the prev. owner installed a Greddy turbo timer and apr bipipe, he must have installed a chip or something else. I go to apr's website and look up the instruction on how to swtich modes between programs. I getin the car turn it on, hold down the set switch and i see the check engine light flashing. OMFG!, it had two programs. One stock and one chipped. I quickly change programs and drive it around and it is a completely different beast. My hands are still shaking. Btw, the car only has 10,200k, and still has the bosch diverter valves. Are there any other aftermarket parts I should look for? Could the bosch diverter valves be the upgraded ones?
