AMDP has developed this EZ-Lynk tuning package specifically for 2020–2022 LM2 Duramax 1500 trucks. EZ-Lynk’s cloud-based platform allows you to flash, update, and data log your truck directly from your smartphone without visiting a shop.

These tunes are designed to improve drivability, throttle response, and overall performance while maintaining factory safety strategies. If issues arise, AMDP can remotely review data logs and make adjustments as needed.

We do not support lope tunes or smoke tunes.

• Includes EZ-Lynk AutoAgent 3 device and AMDP custom tuning
• Three power levels to match your driving and performance goals
• Improved throttle response to eliminate dead pedal feel
• Optional TCM tuning for smoother shifts, better torque delivery, and improved towing performance
• Transmission optimization with refined shift points, faster shifts, and improved torque converter lockup
• Cloud-based tuning for easy flashing, updates, and data logging from anywhere
• Factory safety backdowns retained to protect the engine and transmission

Level 1 – Optimized Stock (0 HP)
