2024-2026 Duramax L5P AMDP HP Tuners MPVI Custom Tuning

Unleash the full potential of your 2024-2026 L5P Duramax diesel engine with AMDP's Custom Tuning solution. Designed for truck enthusiasts who demand reliable, high-performance upgrades, this tuning package delivers optimized power and efficiency while maintaining durability. Whether you're towing heavy loads or seeking a more responsive driving experience, AMDP's tuning elevates your Duramax to meet your needs.

Key Features:

  • Five Distinct Power Levels: Select from five power levels, ranging from stock to an impressive 150 horsepower gain, tailored for everything from daily driving to heavy-duty tasks.
    • Level 1: 30 HP over stock – Ideal for improved fuel efficiency and light towing.
    • Level 2: 60 HP over stock – Enhanced power for moderate towing and daily performance.
    • Level 3: 90 HP over stock – Balanced for aggressive driving and light towing.
    • Level 4: 120 HP over stock – High-performance tune for demanding street driving.
    • Level 5: 150 HP over stock – Maximum power for extreme performance and racing applications.
  • RTD4/MPVI4 Device Integration: Powered by HP Tuners' RTD4 or MPVI4 device on their Tune Delivery Network (TDN), this system operates like a secure, cloud-based EZ Lynk platform, offering seamless over-the-air updates and remote tuning delivery for maximum convenience.
  • SOTF Now Available: Shift on the fly between all five power levels using your factory steering wheel controls, so no extra switch is needed. Our steering wheel controlled SOTF is the most innovative and unique method in the industry, giving you clean, factory style control of your tune right from the wheel.
  • Enhanced Performance: Enjoy smoother power delivery, sharper throttle response, and improved engine efficiency, making your Duramax more capable and engaging on the road or trail.
  • Removed Speed Limiter: Enjoy meeting new friends in traffic enforcement with our removed speed limiters.

Choose Your Vane Control and Fueling:

  • Vane Control: Choose between Rumble or Hiss idle with our tuning. Rumble holds the turbo vanes open at idle for a deep diesel rumble. Hiss closes the vanes at idle for that turbo hiss and quicker spool off idle.
  • Fueling: Standard fueling is recommended for daily driving and towing. LBF (low boost fueling) adds fuel at lower RPM and boost for more low end power and will smoke more.
  • How to Choose: No extra cost and nothing to select. Want Hiss or LBF? Just mention it in the order notes. If nothing is noted, your tune is built with Rumble and Standard fueling.

How SOTF Works:

  • Open tune selection: Hold cruise cancel for 1.5 seconds.
  • Pick your level: Use cruise plus or cruise minus to move between tunes. Tap cancel or wait 6 seconds to close the menu.
  • Smoke control (LBF): Outside tune selection, hold cruise cancel for 3 seconds to switch. Gray is standard fueling and green is LBF.
  • Rumble or Hiss: Outside tune selection, hold cruise up for 3 seconds to switch. You will see 10 or 20 flash and hear the exhaust note change.
  • Settings stay saved: Your tune, LBF and Rumble or Hiss choices stay set until you change them.
  • Hide the display: Hold cruise cancel for 5 seconds. Your tune stays locked in. Hold cancel for 1.5 seconds to show it again.
  • Cruise control note: On trucks without adaptive cruise, hide the tune display to see your cruise set speed. With adaptive cruise, the number may flash after you turn cruise off, and it resets the next time you open tune selection.
