What is up with mags consistency??

if you bought a new regulator seat, do not take apart the reg unless you experiance velocity problems, just leave it alone

There are really only 2 things that will cause erratic velocities. Reg seat and the valve piston. Take them both out, clean them, and reinsert or replace. That should do the trick.
