would appreciate some input, trying to tune a 2009 vette and having issues with fuel trims, I have smoke tested the car, found small injector leak, fixed it, found a cracked coil pack and replaced it with new plugs, smoke tested again. I cant find anything mechanical wrong with the car. but now matter what I do I cannot get the fuel trims on, stft go way out of wack and bank 1 is running 10% to 18% different than bank 2. the only other thing I can think of is an 02 sensor is bad. I didn't build the car but am trying to help a friend out. attached is the log and part throttle tuning file. any input would be appreciated.
