I'm going to Nelson Performance in San Antonio in the morning and I need to know whats best for tune in my DD 4.8 Silverado Z71 with TB spacer and K&N. I will do the exhaust next week.

There is no way for anyone to say whats the best tune, a tune is made for each vehicle individually. Let your tuner choose the best tune for what you want. If your doing the exhaust I would wait for the tune until all of your mods are done because that is the only way you can take advantage of the parts you put on.

I agree^ first get aaall your mods done before tuning your truck. That way you will save your self a few bucks of a re-tune. Nelson Performance know their tuning, they do great work!
