I have one, currently (uninstalled) from my raptor due to what appears to be some sort of sluggish effect that happens from standing launches doesn't happen 100% of the time. But I had the same issue with the same Jb4 unit in my bronco. I sold the bronco took the unit off and put it on my raptor to try it out. I will note (only on map one, and no obd connection) but I really don't think the obdII connection would stop the random sluggish problem, I could be wrong. I will not denounce the product 100%, but I also do not see a noticeable enough positive difference from it if only map 1.
