Follow your heart and your budget. Whatever you do, think it through and make a plan that covers the before, during and after, including potential hiccups (like unplanned fuel system upgrades or tune issues). Bear in mind, too, that there are a number of great tuners out there, and on SVTPerformance, who can provide a good, safe, remote tune. You don't necessarily have to have it done locally, although that would be preferred IF the tuner is top notch and experienced with these motors.
