Looks like it has an APR chip. It would not surprise me if the soldering was going bad.

M is the 2001.5 model year ecu and T is the 2002 model year, functionally no difference.

running rich codes came back on.

So I took the car to another dealer and they said the thottle body boot was leaking. After a quick google I saw this is a common problem with these cars. I have the car for a day now and no check engine light anymore. Hope this fixes all the problems. Dealer charged $600....I have a feeling this took them 30 minutes to change....

Only one code left.....P0011.....cam position advanced.....no issues with the car running I hope it's just a sensor. This happened after I brought it back from the dealer I did not have this code before. And the dealership is not returning phone calls.....

If you paid with a CC dispute the charge. They caused the fault and until they make it go away they are responsible.

Where do you live?? I could possibly help if you were near by. I've been working on this cars for a real long time and the issues that your having sounds like you need an expert. It could be a timing issue or even bad gas or even both. I could recommend you first starting out by checking for boost leaks. If no leaks are present you need to check timing and fuel.
