Unleash the performance potential of your medium-duty truck with AMDP Custom Tuning for the 2024–2026 L5D Duramax. Engineered for those who demand more from their Kodiak or TopKick, this HP Tuners-based solution optimizes power delivery and efficiency while maintaining the durability these trucks are known for. By utilizing the HP Tuners Tune Delivery Network (TDN), you get a cloud-based tuning experience similar to EZ LYNK, allowing for remote delivery and seamless updates. Whether you are battling a speed limiter on the highway or looking for better throttle response while hauling heavy loads, AMDP's precision calibrations transform the L5D from a sluggish work truck into a responsive, high-capacity machine.

ECM Unlock: Your factory ECM must be unlocked by HP Tuners via their send-in service prior to tuning.
