It's safe to say you don't have any leaks or turbo issues, plug that hose back in with the edge on level 2 and see what boost #s you get. The adjustment I'm not sure if it's clockwise or counterclockwise on the rod.
To me, it still sounds like your level 1 was close to stock, if not stock since going up to level 2 nets you almost +10PSI more boost with the wastegate out of the equation.
Make sure your level 1 on your edge actually supposed to be power adder, and not just a trans tune or something along those lines.
