I installed this about 2 weeks ago. I used a lift and it took literally 10 minutes. I didn't have to remove or unbolt anything I ran the harness through the heat shield cover and used a small rod to fish it through. I unbolted 2 screws that appeared to do nothing to mount the little controllers to.

This does actually throw codes, it wont show a check engine light but when I used the code reader on JB4 it shows

138110
138111

which seem to be codes for the exhaust valves.

I can confirm it does open the exhaust valve all the way at all times, I made a mistake when ordering mine and forgot to opt for "open" and "oem" control so I got the default "open" and "closed" with no inbetween.

I'm still waiting on my Valvetronic midpipe and I think paired with this controller it should be the best combo since oem never actually opens the flap all the way and modulates it depending on speed and rpm.
