Take the 2 black plastic insert bits you got with it out and wind in your reg before gassing up and re chrono if you put them in. The black inserts are designed to reduce FPS for reballs. Also check all the orings in the new bolt and can are good / there, as mine was missing one out the packet so i swapped it from the old can.
