Hey dude just got my Echo 1 p90, and im having a similar issue, when i fill the mag more than 75 rounds it does exactly what yours is then when its at about 55-65 rounds itwill start shooting normally, from my experience this is a compression problem between the cylinder head, air seal nozzle, and hop up chamber, either of them can cause problems. if you figure it out let me know please, i myself am going to do a complete take down to figure it out!
Just wondering, did you ever get it fixed? i have the same prob with my e90

there might be an imperfection in your barrel

air compression problem. check to make sure your cylinder is sealed properly and make sure your piston head isnt cracked.
