info about car: first gen doc race single kit 6266 gen2 bb. NTK 02 sensors. index 12 injectors. 2 step colder plugs and n55 coil packs. e85 with EOS port injection AIC1 controller. Motiv boostbox and AIC1 controller. DCT transmission. Dual lpfp.

Have been chasing an 02 issue. I know the kit is notorious for burning 02s but after new 02s twice problem persist immediately after resetting adaptations. The car goes lean WOT always post shift. Start of the log looks good to me. No misfires that i feel. fuel pressure looks okay from what I understand. logs below.
