1. Edge Products CTS3 Insight CS2: Best Overall
The Edge CTS3 Insight CS2 is a top performer in our evaluation, offering a significant power increase while keeping you informed with real-time data. In our research, owner feedback highlights its ease of use and the safety of monitoring critical engine parameters like EGT and boost. The preloaded tunes are well-calibrated for various driving needs, from towing to daily commuting.
However, the upfront investment is substantial compared to simple plug-and-play modules. If you prefer a no-frills budget option or have a stock truck that rarely works hard, this may be overkill. It’s best for owners who want maximum control and data visibility.
- Combines tuner and gauge display in one unit
- Preloaded tunes for towing, economy, and performance
- Monitors EGT, boost, and transmission temps
Pros: Intuitive touchscreen interface; Comprehensive monitoring prevents overheating
Cons: Higher price point than basic chips
2. Bully Dog BDX Performance Tuner: Best Value
The Bully Dog BDX delivers impressive horsepower and torque gains at a competitive price point. Our research shows that owners appreciate the GPS-based automatic tuning, which adjusts parameters based on altitude and driving style. The touchscreen is responsive, and the included tunes are dyno-verified for reliability.
On the downside, the GPS feature can sometimes lag in remote areas, and the screen brightness may be insufficient in direct sunlight. If you primarily drive in urban areas with strong GPS coverage, this is a solid mid-range choice. Those who need absolute simplicity might prefer a basic chip instead.
- GPS-based automatic tuning adjusts for altitude and driving conditions
- Includes dyno-verified tune files
- Backlit display for night use
Pros: Excellent power gains for the price; GPS tuning optimizes performance on the fly
Cons: Some users report occasional GPS signal lag
3. SCT Performance BDX Tuner: Best for Custom Tuning
The SCT BDX is a favorite among enthusiasts who want to fine-tune their Dodge diesel. In our evaluation, the ability to have custom tunes written by experienced calibrators stands out. The preloaded tunes are solid, but the real value is in the data logging and customization options. Owner feedback praises the power delivery and reliability when using reputable tuners.
However, this is not a plug-and-play solution for everyone. Beginners may find the interface less intuitive, and the cost of custom tunes adds up. If you are not interested in tweaking parameters or visiting a dyno tuner, a simpler chip may be more appropriate.
- Allows custom tuning by professional calibrators
- Preloaded with SCT performance tunes
- Data logging for diagnostics
Pros: Highly customizable for advanced users; Strong safety features with parameter limits
Cons: Requires some technical knowledge to maximize
4. Quadzilla Commander: Best for 5.9L Cummins
The Quadzilla Commander is tailored for the 5.9L Cummins, offering a convenient way to adjust tuning via a smartphone app. Our research indicates that owners appreciate the ability to switch tunes without a laptop. The safety features help protect the engine from excessive heat and pressure.
However, durability concerns arise from some owners reporting app crashes or Bluetooth dropouts. Additionally, the power gains are modest compared to newer tuners. If you have a 5.9L and want a simple, adjustable solution, this is a good match. For 6.7L engines or those seeking maximum power, look elsewhere.
- Smartphone app control for tuning on the fly
- Specifically designed for 5.9L Cummins engines
- Includes safety limits for EGT and boost
Pros: Convenient app-based adjustments; Good power gains for older 5.9L engines
Cons: App connectivity issues reported by some users
5. Mopar Performance Power Adder Kit: Best OEM Upgrade
The Mopar Performance Power Adder Kit is the safest choice for owners who want a modest power increase without voiding their warranty. In our evaluation, the CARB compliance and factory engineering make it a worry-free upgrade. Installation is straightforward, and the kit includes everything needed.
That said, the power gain is minimal when stacked against dedicated tuners. Enthusiasts seeking significant performance will be disappointed. If you prioritize reliability and legal compliance over raw power, this kit is ideal. For those wanting more aggressive tuning, skip this one.
- Factory engineered and backed by Mopar warranty
- CARB compliant for emissions legality
- Simple installation with no tuning required
Pros: Maintains factory reliability and warranty; Emissions legal in all 50 states
Cons: Modest power gain compared to aftermarket tuners
6. Edge Products Juice with Attitude: Best for Towing
The Edge Juice with Attitude is a classic choice for Dodge diesel owners who tow frequently. Our research shows that the tow tune is well-regarded for keeping exhaust gas temperatures in check. The rotary dial allows easy switching between power levels without distractions.
However, the unit lacks modern features like a display or smartphone connectivity. Some owners report that the switch can be finicky after years of use. If you want a simple, reliable tuner for towing and don’t need flashy features, this is a solid pick. For those who want data monitoring, consider the CTS3 instead.
- Six power levels including a dedicated tow tune
- Includes EGT probe and boost sensor
- Simple rotary dial control
Pros: Tow tune helps maintain safe EGTs while hauling; Affordable entry into Edge tuning
Cons: Older technology, no touchscreen or app
7. GDP Tuning GDP+ Module: Best Plug-and-Play
The GDP+ Module is the ultimate plug-and-play solution for those who want a quick power boost without any complexity. In our evaluation, installation takes minutes and requires no technical skills. The module is pre-programmed to provide a mild increase in horsepower and torque.
However, the lack of adjustability means you cannot tailor the tune to your specific driving needs. Some owner reviews mention inconsistent performance and occasional check engine lights. If you want a no-hassle upgrade and are okay with modest gains, this module works. For serious performance or towing, a full tuner is a better investment.
- Simple installation: unplug sensor, plug in module
- Pre-programmed for mild performance increase
- Compact design fits in tight engine bays
Pros: Easiest installation of any chip; No tuning knowledge needed
Cons: Limited adjustability and safety features
Frequently Asked Questions
What is the difference between a chip and a tuner?
A chip is a hardware module that intercepts sensor signals to modify engine parameters, often offering limited adjustability. A tuner (or programmer) is a device that reprograms the ECU and usually provides multiple tune levels, data monitoring, and diagnostic capabilities. Tuners generally offer more power and safety features.
Will a chip void my Dodge diesel warranty?
Aftermarket chips and tuners can void your factory warranty if they cause damage or are detected by the dealer. Some products, like the Mopar Power Adder Kit, are designed to maintain warranty coverage. Always check with your dealer and read the Magnuson-Moss Warranty Act for your rights.
Can I use a chip on a 6.7L Cummins?
Yes, many chips and tuners are compatible with 6.7L Cummins engines. However, the 6.7L has more complex emissions systems, so choose a tuner that offers emissions-friendly tunes or is CARB compliant if required in your state. Some older chips may only work with 5.9L models.
How much horsepower can I expect from a chip?
Horsepower gains vary by product and engine. Typical gains range from 50 to 120 HP depending on the tune and whether you have supporting modifications. Aggressive tunes can push higher numbers but may increase risk of engine damage without proper monitoring.
Do I need to monitor EGT with a chip?
Yes, monitoring exhaust gas temperature (EGT) is critical when adding power to a diesel. Excessive EGT can damage pistons and turbochargers. Many tuners include EGT probes and safety limits. If your chip doesn’t have monitoring, consider adding a gauge.
Our Verdict
After comparing specifications, safety features, and owner feedback, the Edge Products CTS3 Insight CS2 earns our top pick for its blend of power, monitoring, and ease of use. For those seeking the best value, the Bully Dog BDX Performance Tuner offers near-top performance at a more accessible price. Choose based on your need for custom tuning versus simplicity.
