I am having an issue with my turbo 2015 civic si when open throttle, car will go very lean and sputter . Not sure what it would be, checked and replaced spark plugs flow tested injectors, made sure fuel pump didn’t lose pressure (by motoring regulator pressure). Motor passed leak down and compression test. Valves are adjusted properly, primary o2 was replaced. replaced the pcm and throttle pedal too. Issue is there regardless of tunes and base maps

log attatched

Post the calibration as well.

heres 2 calibrations. issue happens on both

Have the fuel tables been properly tuned? The log has stand still revs so I assume your issue is that you are reving the car at a standstill and it sputters.

Yeah as far as I know they were properly tuned. I was at the dyno probably about a month ago and was having this issue on the dyno too. Tuner couldn’t figure it out. It does it also when driving
