Catless DP O2 issues
I have a X5M with oem gutted cats with Velos personal tune.
The tune is not hiding my 02 p0420 bank one cel. Thinking about doing the spacer fouler plug to separate The 02 farther down. Anyone know which side I need to do? Passenger or driver side? Btw I replaced all 4 02 hoping the velos tune would remove it but it hasnt |
