I was getting sick of the lag in throttle response, taking off from stops. I went with a Soler bluetooth controller, and it's a lot better (it still lags sometimes, but I think it's more of a case of a quick stop, then applying the gas quickly). I use the Sport 5 setting most often - I found that higher Sport settings often induced a little tire spin, leaving stop signs.
It's fairly easy to install, they tell you which tools to use to remove the gas pedal assembly, after that it's a quick plug & play.
I had an occasion to contact customer service shortly after purchase, and they were very responsive. And you've probably seen that they also have a presence here on this forum.
I had forgotten about the anti-theft feature until it was brought up in that other thread recently about Pedal Commander. I am definitely going to start using it as another layer of protection!
I did have one issue with it, but it was my own fault. Not too long after installing it, I decided to try changing to a different mode through the app while cruising down the interstate with the cruise control engaged. The app froze on me, and close out. Shortly after, I noticed that I had no throttle response. As I was approaching my exit, I pulled over onto the shoulder. I shut off the car and restarted it, and it reset. I probably could have reset it through the controller itself as well, but didn't think of it. Lesson learned, don't play with the app while driving (which is also not recommended in the instructions).
