I ve had this problem the last 3 times I went to get it tuned, right around 4600rpms it goes lean, I replaced the maf with a ba2400 and I got 2 255 fuel pumps and changed the fuel filter, yesterday it still did it. My tuner did a run to collect the data and it starts pulling fuel at 4600rpms nothing he could do would change it. I hope that makes sense. Im not sure if this is related but my pcm cant read all the airflow either he has a way around that I didnt know if that would help figuring out the first fuel issue. Thanks
