Had the lethal performance off-road hpipe with a steeda tune installed recently and now I'm getting a CEL p219a (bank 1 air/fuel ratio imbalance). Anyone had any experience with this or know what could be causing it? I called steeda and they said it could be bad o2 sensors.

Use your tuner to clear the code and see if it comes back. Mine did the same thing, Steeda tune with cat deletes (welding to make sure of no leaks). I cleared the CEL because the car seemed to be running fine and havent seen it since. I put 2000 miles on it for a road trip last week and it still hasn't come back on. When I get time I'll datalog and send it to Steeda to double check the tune.
