I'm not sure if the logs I've captured show an accurate representation. But I have had this issues since I paid the first tuner to tune the truck after the cam. Its sounds like a back fire/ Knock to me. The computer picks it up as knock and the timing sways.
I haven't been able to resolve this and have paid a couple of tuners and haven't had any luck.
I have have tried some idle tuning and idle Torque but it doesn't seem to make any difference.
Any help would be appreciated.
Log and tune attached.
