What Is Custom Tuning?

Custom Tuning changes the ECM (Engine Control Module aka Engine Computer) parameters that control how your engine runs. This means a custom tuner can do things like increase the fuel delivered in a specific situation to add power, while pulling fuel quantity in another to still keep your truck safe. Here at Calibrated Power Solutions, our Custom Diesel Tuning gives you an increase in horsepower and torque while still maintaining OEM levels of reliability.
