I have kooks lt's with ory, msd wires, mac cat back, and a volant air intake. I was thinking about getting a predator and I was wondering how much can I lean out the fuel without problems, and can I save on gas milage to make up the cost of running premium over regular? Also do I have to run premium with a predator?

the PCM is in closed loop mood during normal operation so whatever you adjust will not affect your everyday milage. if it needs fuel to keep the correct a/f ratio, it will take it.
