Okay your STFT are horrible, the banks are basically doing the exact opposite of each other. Looks to start as soon as you go into boost.
No codes during a pull like this? Check for obvious vacuum leaks, could also be a faulty o2.
DO NOT do pulls any further. Youre leaning out cylinders and these engines will let go. Trust I just replaced mine for a bad o2 while logging for my tuner.
INPA or ISTA has tools tou can download to check o2s for free. Smoke machines on Amazon are very affordable. Time to roll up the sleeves and start checking.
Would be smart to pull your plugs see if the injectors for 4,5,6 are leaking. Or are clogged.
