I have watched a few video's on youtube about this little tuner that connects directly to the vehicle pcm. It has several setting to run with, the ability to change on the fly, and running with mds. I was wondering if anyone on here has tried it. The youtube videos say that you can just take the chip off and install the factory one and it won't leave any messages on it. Not sure about that but its what they claim
Anyone out there used it on their 2019
