What are your LTFT for both banks?
my bank 1 is -1% to -3%, bank 2 is 3% to 7%.
Car runs great, except with the tune i get some pinging. I believe is bank 2 running lean. But no codes so im not sure where to start.
Go to this thread:

im gonna request a tightening on bank 2 intake manifold bolts on my next oil change.
