E78 Cam phasing & scan data

I have enough gray hair and about to be bald at this rate.....
2014 2500HD 6.0, OS of 12657063. Wanted to see how cam position effected power and fuel mpg before really getting into the vve tuning aspects. For the life of me the scan data doesn't correspond to what is being commanded in the tune. I've zero'd out tables b7936 and b7934 and left b7935 stock because I'm at Med baro altitude. I've also zero'd out b5154 and still no dice.
Another issue is that the scan will not link to any of the data in the tune. It's become a tedious and frustrating event with this gas pig of mine.
At this point I feel like the this OS is not able to be tuned with the current tables available.
looking for some ideas....different os, sell the truck, be happy to not pass every gas station and continue to dream of supercharging it?
Running v8.2.5.322, v7.5.10.329

You can add/create pid->table links in the file E78_Link_ini.

I will give that a shot!
Thanks

Find the table id you're interested in, and for either row or column (whichever axis matches your pid), add the pid you want to use for linking (use comma as separator)...

save the link ini file, and restart tunetool.
