NPP Fuse
Does anyone know if you can still pull fuse 51 to keep the NPP valves open all the time on the 2020 ZL1 without getting a CEL?
Thanks |

I did it on my 2020 2SS with no issues, I ended up putting it back in as I really couldn't tell any differences (vs. just "locking" "Engine Sound" in "Track" mode using the entertainment screen)...

I pulled the fuse on my 2017 ZL1 a while back and it didn’t seem to make a real noticeable difference in sound so I put it back in and set the exhaust to Track mode in the DIC. Now when I had my 2016 2SS it really made a difference probably due to the Cold Air Inductions CAI that I installed along with the fuse pull.

I pulled it and the blind spot indicators on the mirrors stopped working. Even after putting the fuse back in. Not like I cared for that anyways.
