What you said in original post was "bet all dfi's done (sic) have this"

IDK what that means either.

All P's in Cali are using the same gas w/o pinging afaik.

My suggestion: put it back to stock and if you still have a problem take it somewhere to have it diagnosed. They don't all do that.

 

I guess there was a typo. DFI's don't have a pinging issue. The noise only happens at low rpm , say if I take the clutch out a bit more than the RPM's can keep up. I'm going to take the ECU back to stock and have it looked at.

Best thing to do.
