With the new 5.0 they have electronic solenoids that act with the oil pressure and a spring on the cam sprocket to adjust the Lsa. The intake and exhaust have their own separate solenoid and galleys to where each can be adjusted how ever and what ever you want, you just need the correct software that gives you access to these tables in the tune. With the factory setup the computer can advance or retard the Lsa as much as 50*!! With the ghost tune it simply advances the cam timing thus causing the lope sound. When installed "straight" up the factory cams would be some choppy mo fo's!!!
