Sport Tune Only L5P (2017-2019)

Calibrated Power Solutions - L5P Tuning Package includes everything you need to tune your 2017-2019 L5P Duramax. This tuning does NOT delete or tamper with emissions equipment, focusing on unlocking the power potential of your truck from the factory. While the rated output for the L5P is 445 HP and 910 ft-lbs of torque, it dyno'd 405 Rear Wheel Horsepower (RWHP) and 850 ft-lbs on Calibrated's loaded chassis dyno. With custom performance tuning, you'll have access to up to +150 RWHP. This package offers total flexibility to switch on the fly while driving between five emissions-intact custom tunes for your 2017, 2018, or 2019 Chevy Silverado or GMC Sierra. No need to plug in to re-flash your truck to change tunes.
