What do you have your reg set at? Set at 300psi the ext should shoot at 280fps. When I recieved my ext my reg was really high and too much pressure acts against the valve it wont stay open long enough therefore your low fps. Look for some info on sweet spotting the reg, in regards to autocockers, it kinda the same thing.
