Honestly by looking at your sign, I would save my money and don't get a tune yet. Your mods seem within the capability of your stock tune and you might be able to get a couple of extra horses, but I doubt you'll notice the difference.
But I don't think you're currently at risk of running to lean and damaging your engine.
Maybe some people that have gotten a tune with the basic bolt ons can chime in, but I doubt they can post any big gains.
You're better of spending your money elsewhere. If you really want it, you could buy a Cobb AP and hope they break VVL.
