The problem is the inconsistencies between tunas. The attitude is: Well this works for me so it "works". Yet, there is little reason to believe, at least that I have seen thus far, as to how they came to that conclusion (other than trial and error). Which is why I stated all you high powered A8 guys need to publicly consolidate your findings, work out a common rationale behind it, and apply it across the board. Yeah, this would upset the tunas - but be realistic about your goals and how you are going to set up the legacy for these cars (because the automagic cars will set the standard) if you want to live and die by the A8. I lived through two decades of BS in the LS world watching the trial and error of fly-by-night tunas and vendors who were really just capitalizing on the ignorance of the customers. If you were smart enough to go to school and get a good job and pay for a Hellcat - you can damn sure learn how to tune your own fucking car. Tunas aren't engineers or scientists <insert your internet credentials here> - they are just the guys who saw and opportunity and took advantage of it. I know this sounds harsh, but it is very much the case.
And then, yes, you have the perpetuation of internet misinformation by the ownership group who choose to pay the Hellcat tax and assume little to no responsibility in comprehending their decisions simply because they paid for a service.
