If you have a 2019 through 2023 L5D Duramax-powered 4500, 5500, or 6500 Silverado, Calibrated Power can now deliver you switch-on-the-fly custom tuning.
It is easy to safely add 125-plus horsepower and 240 lb-ft of torque to your truck with Calibrated Power’s remote tuning. Your truck will no longer struggle to maintain speed on the highway or have sluggish acceleration when towing. In just 30 minutes, you will be able to unlock and flash tuning onto your truck’s existing ECM.
Calibrated’s tuning will allow you to have total flexibility to switch between custom tune files on the fly, giving you the power for heavy towing, fun daily driving, or ultimate engine performance.
Calibrated Power knows the number one issue talked about with these trucks is a lack of power, especially when it comes to towing. This custom tuning provides a significantly wider torque curve compared to stock. This allows you to access more power across the entire engine RPM range.
The additional low-end torque you’ll get makes moving heavy loads a breeze. Plus, it allows the engine to shift up and throttle back when driving on the highway. This can even result in better fuel mileage. With all of that additional power you get, there’s no more struggling to maintain your speed while towing either. Just sit back and enjoy being able to use your cruise control again.
With more than 100 engine parameter adjustments made, custom tuning provides the most complete and powerful engine tuning possible. In addition, your engine and drivetrain safety are Calibrated’s top priority. In fact, they explain that keeping factory EGT limiters and other safety features in place is part of the tune, ensuring your engine stays protected. Calibrated Power has more than 15 years of custom tuning experience. It is an understatement to say they know what these trucks are capable of and how much power they can safely handle.
