Dodge Challenger MDS Delete Service – MoPower ECU Programming

The Dodge Challenger HEMI is built for performance, but the factory Multi-Displacement System (MDS) can create reliability problems such as lifter failure, ticking noises, and inconsistent power delivery. Our MDS Delete service permanently disables cylinder deactivation in your PCM, keeping all 8 cylinders active at all times.

Why Choose an MDS Delete?

• Prevents common HEMI lifter and camshaft failures
• Delivers consistent full-time V8 power
• Eliminates the rough transitions and drone from MDS activation
• Improves throttle response and smooths drivability
• Better long-term reliability with performance upgrades

MoPower MDS Delete Features

• Permanent removal of MDS cylinder deactivation
• OEM PCM flash with MDS disabled
• Works on both 5.7L and 6.4L HEMI-equipped Dodge Challengers
• Supports models from 2009–2023
• Optional pairing with custom MoPower performance tunes

How It Works

Send your PCM to MoPower Calibrations, or visit an authorized MoPower tuner. We reprogram your factory ECU to permanently disable MDS. This is a software-only solution — no wiring mods or add-on boxes required.
