From all I've read (and I'm no expert just spent a lot of time reading) most of the issues with #8 were traced back to two things:

1. Tuners in the very beginning not knowing what they were doing and changing the pcm to cause lean conditions and altering knock sensors.
2. A bad batch of PCMs seemingly put on cars that were built in the middle of 2011. I believe the particular pcm code was: ZFK0
