11.89 at 1600' positive feet DA, the vid is in my sig. 11.97 at 2100' DA with just the mani's. when I added the Ypipe I ran 11.97 again but at 500' higher (2600') DA. I would love to run in negative DA just once. I never hit 11's with just the pulley. 12.02 was the closest I got. Again with DA above 2000' feet.
