The best way to not only maximize but increase horsepower and torque on your 2017 GMC Sierra 5.3L V8 would involve installing a cold air intake, performance exhaust system, in addition to a performance chip tuner. Using these components will allow your engine to breath better and perform at it's peak output which will increase not only power but also fuel efficiency.

For a cold air intake compatible with your vehicle, I recommend using the Airaid MXP Cold Air Intake System part # AR200-285 as this is one of the most cost effective air intakes on the market. For a performance exhaust system that is compatible with your vehicle, I recommend using the MagnaFlow Cat-Back Exhaust System part # MF15278 for regular cab models and part # MF15268 for both crew and double cab models. A stainless steel cat back exhaust system will increase both horsepower and torque in addition to providing a rear dual exit for a smooth throaty sound. The kit comes with everything needed for installing with no welding required.

In order to obtain the maximum performance of both your vehicle and added performance parts, I recommend install a performance tuner chip such as the Superchips Flashpaq F5 Performance Tuner part # SU2845 as this tuner in addition to the cold air intake and exhaust will increase your vehicle's horsepower and torque up to 30 HP and 42 Ft-Lb respectively.
