After putting on a D&D Y Pipe my M8 is loading up at idle. It didn't do it before so I assume it is the Y Pipe that is causing the problem. It really sucks if you are lining up to race a buddy and the sled is idleing for more than 10 seconds and you go and pin the throttle and it sputters and burps and your buddy takes off and you are left there looking foolish. Otherwise the sled runs and responds terrific. Has anyone else had this problem and if so is there an easy fix?
