Is this the final chapter of The A6 of Death? Stay Tuned...
Well I called the audi tech at his house today, yea that was kinda awkward but he told me to. He said that my car had either had the ECM replaced and it was programmed wrong or my car has had an air leak for so long that the car thinks that this is normal behavior so now that there are no leaks the car is still trying to compensate for the air leak. Does anyone know if the dealer or audi engineering can flash the ECM with new software or am I going to have to go to the junkyard on this one?

I suppose those scenarios are possible, but both sound a bit implausible to me.
First, you have a '98, 2.8. True, the ECU can adapt to air/fuel conditions, but once things are fixed it should adapt back. There's not permanent memory. Even if there was, it's easily resettable to scratch with factory tools or a VAG-Com.
Second, being a normally aspirated 2.8, few if any tuner programs exist. Who could have possibly changed the code, and for what reason? Certainly crashed valves and new top end wouldn't warrant it. And yes, I would surmise that the dealer could indeed reflash it unless it's physically damaged.
Again, possible, but so was the 2nd gunman on the grassy knoll.
But, let's chase this down. What is the ECU revision (letter code) in the car now? Compare that with other '98s to see if it's even correct. And assuming it's the correct version and you think it's physically bad, the good news is that it shouldn't be that hard to find a used one from national junk yards -- unlike some other C5 variants like 6-speed 2.7Ts.
Best of luck. I just think there's a simple explanation buried here, and the most likely is what you wrote below... the person who rebuilt the head just didn't put things together correctly.
But that would not explain why it's been OK for the year+ you've been driving it up until now, would it?? Logical inference is your friend.
