I'll get a grasp around the mathematical equation eventually. I'm just trying to understand that raising the value delays the injection cycle and people have(generally) seen smoother idle and less fuel smell with overlapping cams. Due to not sucking unburned fuel out of the exhaust, even though GM designed it to spray on a closed intake valve to help atomization(which it will no longer do). I'm still doing a lot of reading and some of the numbers seem awkward to me, but I'm pretty good with numbers so I'll get it lolol

Thanks
