I actually really like this programmer. It's so archaic in its simplicity it feels like a device from 1987. But it works. and it works well. I was pleasantly surprised that just by installing the standard upgrade tune for my 300C SRT , the car not only was improved in performance, but it just ran better. It idles better and it honestly appears to just run smoother. It's noticeable the difference I've gotten in throttle response, but I actually like it best because the car just runs better.
