Hi,
I followed your professional discussions and replies.
I have Excessive Feedback knock reaching -11.95, at low RPM. It is been 4 months now. Don't know if it is false knock.
Tuner could not figure out the issue.
WRX 2015, JPIPE,CAT BACK , ECBS. CVT.
Appreciate if it is possible to help me out, attached the COBB Log File.
