i recently bought a new orracle e-class marker. i went to chrono it and the velociy spiked up and down. i was hoping the difference would be +/- 7 fps or below but it wasnt so? what should i do to remedy this? should i buy a new regulator? a new barrel? (im using the stock one right now) and how do u know how much air is going to the marker cuz i dont want to damage my gun. plz help!! no flaming plz cuz im a noob. 
(im planning to upgrade my reg to a sidewinder, the barrel to a boomstick)<----- good choice? plz help.
