OK, I wanted to add some additional information....I have never heard of BBI (what do I know right?) so I looked on youtube and there is a video, for anyone that does not know it, of the two founders who appear to be two x-Bosch employees from the common rail injector team and they have the complete German accent to go along with it. This is a big selling point for me because they must have a clue about what they are doing. Thanks to OP for starting this thread, I learned something and will try BBI when I'm ready.
