When I hit 6000rpm I get the check engine light coming on. 4 beeps then it goes away when I throttle down, it goes away. I can go over 6000 with out it coming on. I drove in the untracked snow and would hit 5800 and it would come on. I was driving the sled locally. I did set my clutch to 1. I am running dynamo joes clutch kit. Any thoughts would help.
