New to this field I have a 5.3 Chevy vortec in a 2007 Silverado with shorty headers and a cold air intake I'm looking for a downloadable tune file to look at and see what works the best and how it's supposed to be done.

Go to hptuners.com tune repository and do search of 5.3 tunes. There are plenty to look at.
