Eliminate Dead Pedal on Your 3.0L LM2 Duramax
The 3.0L LM2 Duramax is an incredible half-ton powerplant, but factory torque management and sluggish throttle response leave a lot to be desired. The AMDP Custom Tuning Support Pack is the ultimate digital upgrade for your existing EZ Lynk AutoAgent 3, delivering expertly crafted calibrations that drastically improve daily drivability, mid-range acceleration, and towing performance without sacrificing factory safety strategies.
AMDP provides three selectable power levels, ranging from an optimized stock file designed purely for throttle response, up to a potent +50HP / +110 lb-ft max-effort tune. Whether you're commuting, hauling a boat, or just want to wake up your 1500, these cloud-delivered files provide clean, reliable power (no lope or smoke tunes are supported).
⚠️ IMPORTANT: This is a digital calibration package. Please checkout using a valid email address. You must already own an EZ Lynk AutoAgent 3 device. Your files are pushed via the Cloud, and we will email you the exact instructions to link your vehicle within 24-48 business hours. Ensure your exact 17-digit VIN is entered correctly above.
Maximize Your Build
Pro Tip: Upgrading to the Lifetime Lynk Package is highly recommended, as it gives you unlimited future tune revisions and updates indefinitely. If you select Add Transmission Tuning, be aware that your factory T93 TCM must first be physically unlocked via the HP Tuners Global B Upgrade Service before the EZ Lynk can flash the AMDP transmission files.
🔥 Power Levels & Tune Options
- Level 1 (Optimized Stock / +0HP): Sharpened throttle response and vastly improved drivability while maintaining factory power output. Ideal for long commutes.
- Level 2 (Performance Daily & Tow / +30HP): Adds +30HP and +70 lb-ft of torque. The sweet spot for mid-range acceleration and towing efficiency.
- Level 3 (Max Performance / +50HP): Delivers up to +50HP and +110 lb-ft of torque for maximum acceleration. (An aftermarket S&B intake is strongly recommended. Not advised for heavy towing).
⚙️ Technical Specs & Requirements
- Hardware Required: An existing EZ Lynk AutoAgent 3 device and CAN-Bus bypass plugs are mandatory to communicate with the vehicle.
- TCM Tuning Requirement: To utilize the optional TCM tuning, your factory T93 TCM must be sent in and unlocked via the HP Tuners T93 Upgrade Service (Global B). You will also need an HP Tuners MPVI3 device and 4 Universal Credits to license it once returned. After licensing, the AMDP files can be flashed via EZ Lynk.
- 4-Week vs Lifetime Support: 4-Week gives you cloud access for one month to flash your truck. Lifetime provides unlimited access to AMDP's cloud library and future updates indefinitely.
