If its not following the coils when you move them around its the plugs. You say you have leaking injectors on bank 2 only? Did you let the car sit overnight then pull each plug and inspect them for fuel smell?
The turbos on my car can keep up to redline. Boost PSI is flat all the way to redline so yea it makes sense for me to rev it out. Might try getting new plugs soon but I think I might as well change injectors too its the most likely culprit i think?

Yes bank 2 is leaking pretty bad in that i can see in logs AFRs won't lean out on throttle lift. Bank 1 leans out but i can see it doesn't lean out perfectly on lower rpm throttle lift either so i probably have some slightly leaking injectors there too. They are index 7 injectors after all which were notorious for issues.
