There has been some chatter on HPTuners that running MAF and a lot of stock everything-else (save for some more radical combinations that need it) is a good way to go. There is even talk of leaving VVE and VVT stock unless your PIDs are showing running into those thresholds. It's a lot of learning...

Make sure you've turned off the temperature variables in your fueling, too. I don't have access to my HPTuners at the moment, but I recall some tables for temperature, among RPMs and such, that you might have to disable, too.

Check that you don't have any exhaust leaks ahead of or around your WB. That will show lean, too, if I recall.

Finally - make sure you update to the current versions in HPTuners. I just learned, that if you are running the older MPVI (which I am), to only run the BETA versions, as, I guess, that's what is compatible and most current. I, too, have been watching GoatRope and some of Tactical, and both are helpful. GR has a couple playlists that would be applicable to us, including the tuning he showcases on HIS truck. There are gems all over many of those videos. Make sure to catch his MAF-tuning from many months ago. It goes through set-up and driving, and changing. His videos help me a lot.
