K&N Intake, new exhaust set up, chip, etc. That adds a little more HP for not too much money. How much horsepower do you want and how much are you willing to spend?

Gsmith- I tuned my 2000 Yukon XL 5.3 with a Hypertech programmer and used the premium fuel tune and a Volant intake. Made a BIG difference. These 5.3 's do not have the torque of the old 350's at lower rpm's. Go to Hypertech website and look at the HP graphs for your model, the premium fuel helps.
