Injector pulse width issue Bank 2 rich

Build details:
350sbc bored 30 over, Summit Flat top pistons W/ 6cc relief, Summit Vortec heads, Melling cam Duration 283/287,
Edelbrock Pro-flo XT Intake w/ 92mm throttle body and 42lb injectors. All controlled with a 0411 ecu.

When I am driving Bank 2 goes totally rich.
I thought it was random but it seems when I am hard on the throttle something goes wrong with Bank 2 and the Pulse Width suddenly jumps on Bank 2, as far as 6ms more than Bank 1.

I have no idea what could cause this and most the time if I turn the engine off and restart it the issues goes away until I'm pretty hard on the throttle.

I would lean towards the ECU being bad or a bad ground being the issue with what I know about vehicles but with being a custom build and tune I am not sure what all could go wrong.
Tomorrow Ill check and run a few more grounds to see if that helps but I'm just seeing if anyone has knowledge on this sort of issue.

not seeing o2 mv looks like bank 2 o2 could be lazy at responding you should log mv too

You should post the tune as well. What conversion package are you using?

I will start to log that but lazy or not wouldn't it reduce the pulse when it does read 50 percent rich too?
