So far the kjet is the only thing that's been problem free with my car, other than the not so great mpg.. If the 160bhp I had rr'd is accurate and I'm pushing more than a standard digi abf then for over engineering the control to make slightly better bhp with less power isn't worth it imo. I've seen a lot of head scratching posts due to the digi setup, my kjet I now understand, and can test and fault find (should I need to) quite easily, digi requires a bit more electrical knowledge which people expecting plug and play don't always have. I like kjet, so does my old school rr man. When optimised it aint so bad...
