After farting around long enough and having Magnuson look at the shops tune and they were like - OMG way messed up I just broke down and bought the stupid smartchips tuner from them for the A4. Its not supposed to lock the pcm and magnuson said its about 97% totally tuned, and I would be able to tweek more out if I wanted to.
bummer, have to put off the exhaust for another month or two now.
