Thats what I thought too. I figured it was a little low at 13.8, not hitting the magical 14.5...But, seeing how solid it was at 13.8 throughout the rpm, and then seeing it recover pretty quickly when I hit the fan with the high beam told me it was worthy, so I did some trimming on it, and fit it into the rear portion of my left scoop by welding a small, and solid tab to the upper threaded scoop tab,and securing the r/r with a bolt into the regulator which I tapped threads into. Works pretty slick
