Need a little advice on a few upgrades?!
I've hit a 2011 gmc z71. 5.3 with a 6-speed. I would like to make some noticeable performance upgrades without going into the motor just yet. Only 19,000 miles on the truck. Any suggestions?

A good tune or a higher stall are the two things I can think that will give you a noticeable improvement over stock without having to tear into the motor. Otherwise just go with the basic bolt-ons.
