    Can you share a log of the lean spikes including bank 1 and bank 2 O2 mv? I'm curious if bank 1 is going lean while bank 2 is still working as normal as mine was doing.

    Not sure if we're logging O2s. I know we were logging injector pw and they were both the same

    Here's the other thread: turbo-Silverado-lean-spikes-stumble

    look at the log file, you will see the WO2LAM1 poking slightly above 1.00 in various places for no real reason, and in some places it pegs high (for example during boost).
