I removed the Edge-supplied boost elbow from my rig the other day and upon inspecting it, I noticed something that I had not seen when I installed it the first time. It has a small hole in the side venting the pressure to atmosphere. I had damaged the fitting a little with the wrench when I installed it and the hole was partially closed. This is a really small hole. I used a small drill bit to open it up again and apparently, I made it a little bigger than it was originally. My max boost used to be around 31 PSI. It's now 35 PSI. This hole is on the side of the fitting not the internal orifice.
