98-05 3800 Supercharged Tuned ECM

Custom Supercharged ECM Tune for 1998–2005 3800 Series II

Built specifically for boosted setups—whether you’re chasing power, response, or a derby-ready monster.

What’s Included:

• ⚡ Boost-optimized timing tables for safe and aggressive spark under boost
• ⛽ Enhanced fueling strategy to support higher airflow and supercharger demand
• 🔥 Raised rev limiter for a wider usable powerband
• 🌡️ Modified temperature thresholds to let it run hotter without going into limp
• 🧹 Unneeded sensors/diagnostics removed
• 🔐 Security/anti-theft fully disabled
• 🚫 Torque management reduction for harder hits and faster response

Compatibility Notes:

This ECM works with a stock 3800 harness, but you’ll still need:

• A push-button start,
• A hotwired fuel pump,
• And for derby use, a hotwired transmission is strongly recommended.

For the cleanest install, pair it with a simplified 3800 swap harness—plug-and-play and derby-proof.

For off-road/competition use only.
