Dodge Ram 1500 MDS Delete Service – MoPower ECU Programming

The Ram 1500 5.7L HEMI is built to work hard, but the factory Multi-Displacement System (MDS) can introduce reliability issues such as lifter failure, ticking, and inconsistent power. Our MDS Delete service permanently disables cylinder deactivation in your PCM so all eight cylinders stay active full-time.

Why Choose an MDS Delete?

• Helps prevent HEMI lifter and camshaft failures
• Delivers consistent V8 power with no MDS transitions
• Smoother drivability and throttle response under load and towing
• Ideal for trucks with performance mods or heavy-duty use

MoPower MDS Delete Features

• Permanently disables MDS via OEM-level PCM reprogramming
• Software-only solution — no wiring or add-on boxes required
• Covers Ram 1500 5.7L HEMI (2003–2023, incl. Classic)
• Optional pairing with MoPower custom performance tuning

How It Works

Ship your PCM to MoPower Calibrations, or visit an authorized MoPower tuner. We flash your factory ECU to disable MDS permanently, restoring full-time V8 operation for improved reliability and confidence whether you’re towing, off-roading, or daily driving.
