Chrysler 300 MDS Delete Service – MoPower ECU Programming

The Chrysler 300 HEMI blends luxury with performance, but the factory Multi-Displacement System (MDS) can cause reliability issues such as lifter failure, ticking noises, and inconsistent power. Our MDS Delete service permanently disables cylinder deactivation in your PCM, keeping all 8 cylinders firing full-time.

Why Choose an MDS Delete?

• Prevents costly HEMI lifter and camshaft failures
• Delivers smooth and consistent V8 power
• Eliminates MDS transitions and unwanted cabin drone
• Improves throttle response and drivability
• Safer long-term reliability, especially with performance upgrades
