Madison: FYI, it's not pulse and glide if there's no glide. Glide = transmission in neutral.

My bet is you simply drove more conservatively overall due to the open pipe, and your improved fuel economy isn't simply from this one tactic.
Personally, I've tried "pulse and bleed" several times in my own non-lean burn, non-hybrid, non-vvt car, and found no benefit over simply driving with load (DWL).
