Upgrading the cam in your Ram truck, Dodge Charger or Challenger or Jeep Grand Cherokee can transform its personality — from a smooth daily driver to a rumbling powerhouse with serious performance gains. But the real magic happens when you pair that hardware upgrade with the right cam tuning. Without proper tuning, you’re leaving horsepower, torque, and drivability on the table. Whether you change your cam for performance or to repair the infamous MDS lifter failure, cam tuning is important.
Why our Stage 2 Custom Cam Tuning Matters
When you install a performance cam, you’re changing how your engine breathes. This affects:
1. Valve timing and lift
2. Air/fuel ratios
3. Idle characteristics
4. Powerband range
A stock ECU tune isn’t designed for these changes, so the engine may run rough, lose low-end torque, or even generate engine codes. Our Stage 2 Cam tuning optimizes these parameters to match your new setup.
Key Steps in our Stage 2 Cam Tuning
1. PCM Unlocking2015+ Ram, Charger, Challenger, and Grand Cherokee have locked PCMs. You’ll need to send yours to a tuner or use an unlock service before making changes.
2. Base Tune Setup
Our tuning will adjust:
1. Idle RPM (often raised for aggressive cams)
2. Spark timing
3. Fuel trims
4. MDS (Multi-Displacement System) disable if deleted
Fine-Tuning for Performance
Using tools like DiabloSport or SCT, our tuning will:
1. Optimize wide-open throttle fueling
2. Adjust cam phaser limits (if applicable)
3. Smooth drivability while keeping that choppy idle you love
4. Dyno or Street Testing
5. Real-world testing ensures the tune delivers both performance and reliability.
Common Cam Tuning Upgrades for Dodge, Chrysler, Jeep or Ram
A. MDS Delete – Prevents cylinder deactivation for consistent performance.
B. Phaser Lock or Limiter – Controls variable cam timing for stability.
Pro Tips for a Successful Tune
Work with a HEMI-experienced tuner such as Hemifever Tuning — HEMI engines have unique quirks that require specialized knowledge. Don’t skip supporting mods — Upgraded valve springs, pushrods, and lifters can prevent costly failures. Plan for fuel quality — Higher octane fuel often unlocks more timing and power.
The Bottom Line
A cam swap in your Ram, Charger, Challenger or Jeep is only half the battle — the right tune is what truly unleashes its potential. Whether you’re chasing quarter-mile times or just want that aggressive idle with smooth drivability, investing in professional cam tuning ensures your truck, car, or Jeep runs strong, sounds mean, and stays reliable.
