Drivers O2 sensor erratic? 2 bar SD 5.3 Turbo
Gents - Details of setup are below. Current tune and log are attached. I am trying to get the idle and PT dialed in close on narrowbands alone. Drivers O2 goes nuts. ** I have checked for exhaust leaks, I have swapped O2's from side to side, I have pulled plugs. The behavior stays consistent on drivers side regardless of sensor change. Appreciate review of my tune and log, and any guidance.
