We had what seems to be that issue you're talking about in 2011 when I put this kit on. The issue for us was the GT101 sensor was not PERFECTLY in line with the trigger wheel. New bracket has since been made. There's no logs of issues with timing or anything. When we had that issue we were seeing RPM logs of 86,000 RPM, 44,000RPM and would be hitting the RPM cut. Sound similar?
