I have a 2017 Raptor I just put this on. Easy to install. However, shortly after a test drive, system threw a 'wrench' indicator warning saying Powertrain Malfunction / Reduced Power along with CEL. Anyone see this? Per previous posts could it be due to wire splicing / needing a tune? My kit didn't need any wire splicing per the youtube video as it came with a plug-in resister.
