I'm having the same problem. First shot is fine then rest drop off, I've recently replaced my board with a blackheart one. The pressure seems to be fine sits around the 200 mark on the guage. Not sure how to fix it as im new to Shockers and electro markers. I'm going to the NvS game. Would the guys at the smartparts stand service it for me? if so how much do you think it would cost?
