I would not expect a custom tune to fix the lean problem you are having. It COULD be caused by faulty O2 sensors or a problem with the throttle position sensor. Possibly, the throttle body needs to be cleaned as well. In any case, don't try to fix an engine problem with a tune (canned or custom).

And, the fact that you have a CAI may be the entire cause. Can you return the intake to stock (or change to the Gotts Mod)?

It will not hurt to unplug and plug the Gryphon back in to cure the display problem. Do it with the ignition key ON.
