I just installed the 1st rev of this tune myself, so more data logging to do. Based on the dyno charts I've seen, daily driver should have a noticeable power increase over stock. That said, I imagine most people getting this are setting DD on a lesser-used mode that may impose other detuning effects. I have mine set with the performance tune in normal drive mode. If I don't get in the throttle, it feels very similar to the stock experience (the Mrs didnt even notice a difference). But when I put my foot in it, it really wakes up. Going in, I wasn't sure I wanted performance as the default, but I have zero regrets.
