Just took firsr test ride at home with my 09 800 with rk tek 925 motor. Runs really strong at varying throttle but kicks code 21 at a short burst of wot. This code is octane code if I'm looking into it right. I'm running straight 110 race gas so I'm a little stumped. Could this actually be reading a knock from another reason. Any help much appreciated

I'm running a boondocker box. From the short ride I had so far rocks is an understatement
