Now owning the Quad and having updated it once, I am sold. So easy to update and those are free for life. So, the way I see it, I have all the options I want. I can go DPF or NO-DPF. There is ECONOMY, 50, 70, 90, and 110 RWHP settings. It does speed limiter, tires, reads and clears codes, AND has a real-time display if you wish to leave it plugged in. All that for around $400.
