Hey guys looking for some advice.Bank 1 is running lean (via widebands) and runs hot on that side. Did a smoke test and there doesn't seem to be any leaks. We are leaning towards an injector issue aren't 100% sure.We swapped both wide bands from side to side to see if that was the issue. The car runs with no miss, so it's hard to diagnose. Just want to see if there is something I am missing (test wise) that could pinpoint the issue. This is new build from the ground up so everything is has it little quirks and is a very angry setup. Any advice will be helpful.

If you had 1 injector not opening your still pushing the air through which would show a lean condition correct? Any of the plugs still look new have you tried checking the header at each tube to see if they are close to the same temp ( temp gun), this may narrow down your search---- best of luck chasing out the gremlins!
PS. Im not the greatest without having it in front of me to tinker with but no one else has answered
