Hi all, just installed a 2 mode cargraphic exhaust valve controller in my 718 GT4. The installation went well. However, upon starting the car, I received a check engine light. Working with the controller, everything seems to be working well. The sport mode on the controller keeps the valves open and on the other mode, the exhaust and the rest of the car feels stick. Considering I have a PSE functionality, I think the vaccine tubes are plugged in correctly. Has anyone else experienced similar issues with the valve controller and have thoughts on possible causes ?
