Video Not Working? Fix It Now

As part of my series on AFR/lambda testing the 900SS I discovered some heavy bogging when grabbing a big handful of throttle. In this video I demonstrate this issue, then I show how one can measure the pump output, and at the end we see how this completely resolved the problem. I should also point out that my pumps were squirting 4cc and 5cc respectively prior to making the final adjustment and then the measurement, which is shown in the video.
