I am running the standard stuff

I have a 2007 (New Body) GMC Sierra SLT Z/71 4X4 Crew Cab, And have done the following changes to the Engine:

GM Low Restriction Intake System (No oiling and looks good, great quality)
Corsa Cat Back System (No Drone, great quality)
Hypertech Energy Max Programmer

Do you guys have any other suggestions for tweaking the power?
