SLP has been hard at work developing the Power Pack systems for 2014 and 2015 General Motors trucks powered by fifth-generation 5.3L and 6.2L engines. SLP engineers have put the Power Packs through extensive testing with development hardware on the dynamometer and in real world conditions where payload and towing are crucial aspects of truck performance.
“At the end of the day, your truck still has to work like a truck, so we engineer our parts to tow as well as haul ass,” says Greg Banish, SLP Calibration Manager. “Our Power Pack Cold Air Kit and Loud Mouth Exhaust for the new 5.3L and 6.2L V8 engines improve performance by up to 23 horsepower and 23 lb-ft of torque, and require no PCM calibration to perform as engineered.”
The SLP Power Pack includes a Blackwing Cold Air Intake and Loud Mouth I Exhaust System. While the stainless steel Loud Mouth I exhaust tone is notably bold and aggressive to the competition, passengers won’t be bothered by a loud or overbearing interior drone.

The 2014 and 2015 GM Truck Power Packs will be available by late summer 2015.
