Your having more problems since installing this kit then I have ever encountered with every car I've owned together.

When I broke my 2nd gear my car also cut off. BUT after a few minuets it was able to start up again. I've never heard of "recovery mode" so that's new to me.

I believe you should reflash your tune into the car and see what happens. I went to royal farms one time sat inside for 10 min. Came out and my car had the worse a/f ration I had ever seen. Re uploaded the tune and she was good to go.

Pull your spark plugs and make sure they are good as well.
