I only found this out when I took mine to wsid for the first time cause I figured less fuel = less weight but that nearly = a dead motor. And like you said it wasnt happening till nearly half track (2nd to 3rd).Leo Link to comment https://www.fordxr6turbo.com/forum/topic/79876-surging-still/#findComment-1227154 Share on other sites More sharing options...
