Bank 2 lean
Bank 2 lean Im posting this here as well because at this point we don't think it's fuel we think mechanical. So im at the dyno and every thing was fine pulled 556hp and now all of a sudden bank 2 is running lean where as bank 1 is greag. They tried new wires, plugs, tested the coils, checked fuel injectors andalso used new o2 sensors. Their isnt any error codes that im aware of it's showing on the dyno screen. So my question is if everything is fine as well as fuel pressue then how is one side lean and the other not if every thing is checking out fine. He literally didn't touch it after he shut it off he turned it back on and the idling was weird which is how we knew something was up. Doesnt make sense to any of us.
If it's all the sudden lean and idling different it has a leak or a problem, that you'll have to look for.
I'd start with checking intake gaskets and injector seals on bank 2 (passenger side)
A random hose or something like that being off should effect both banks. That's why I said intake and injector seals

Based on OP description I would look for things that could be affected by heat cycles. Exhaust and exhaust gaskets would be at top of list.

I just went through this. Read my 0171 code thread for some insight. Check the grounds first. I found my problem to be at the coil pack harness plug. Some brake cleaner and dielectric grease cured the plugin. The code reading turned out to be a false positive. Hope this helps.
