Hey guys, just recently picked up an 01 Audi s4, I haven't ever done my own tunes via computer, but I went to school for automotive high performance, so I have done some dyno tuning on few carburetor engines. This is my first Audi, I have had 2 BMWs prior to this and prior to those a Camaro and firebird. I had the firebird built to a low 12 second car, so its about time I start tinkering with my ride again, I'm excited to tune my car myself and any help will be much appreciated!
