I installed a whipple 3.0 on my 2019 Silverado 1500 6.2L with the whipple tune. I initially had issues with the B2S2 o2 sensor. After warm up, it would stay at 1.107v and never fluctuated which generated the P0158 which I could never fix. Since then, I have had the following DTC's
P0137 - O2 Circuit Low Voltage (Bank 1, Sensor 2) (Current)
P014A - O2 Sensor Delayed Response - Rich to Lean (Bank 2 Sensor 2) (Pending, Current, Permanent)
P0158 - O2 Circuit High Voltage (Bank 2, Sensor 2) (Pending, Current, Permanent)
P0171 - System Too Lean (Bank 1) (Current, Permanent)
P0174 - System Too Lean (Bank 2) (Current, Permanent)
P2270 (Pending, Current, Permanent)
I have a rough running engine between 1.5-2.5 rpm which gets worse under load. Below is the Freeze frame date from vcm scanner.

I have triple checked everything on the install. The only variables are the ECM that I had swapped and unlocked from Hp tuners and the whipple tune. Could either one of these account all the DTC's I am having. If not, what should I try replacing?

Any help would be great,
