The Ultimate Buying Guide for Your 2019 Ram 1500 5.7L Hemi Tuner
Choosing the right performance tuner for your 2019 Ram 1500 equipped with the mighty 5.7L Hemi engine can unlock hidden power and improve your truck’s driving experience. This guide helps you sort through the options to find the best fit for your needs.
Key Features to Look For
When shopping for a tuner, certain features make a big difference in performance and usability. Look for these top items:
- Pre-Loaded Tunes: Good tuners come with ready-to-use performance maps (tunes) for different fuel types (like 91 octane or 93 octane) and driving styles (like towing or economy). This lets you flash your truck quickly.
- Custom Tuning Capability: If you plan future upgrades (like a cold air intake or headers), ensure the device supports custom tuning from professional tuners.
- Live Data Monitoring: The best units let you watch vital engine stats in real-time, such as air/fuel ratio, coolant temperature, and horsepower. This helps you monitor your engine’s health.
- Feature Unlock/PCM Swap: Some tuners can unlock features that the factory software locks down. Check if the tuner requires you to send your truck’s computer (PCM) away for modification, as this adds downtime.
- Tire Size/Gear Ratio Adjustment: After changing tire size or gearing, you must recalibrate the speedometer. A quality tuner handles this easily.
Important Materials and Construction
While the software is key, the physical device matters too.
Most handheld tuners use durable plastic casings designed to handle the vibrations and temperature swings inside a truck cab. Look for clear, bright touchscreens. Some premium devices feature ruggedized casings for off-road use. Ensure the connecting cable feels sturdy; this cable links the tuner to your truck’s OBD-II port.
Factors That Improve or Reduce Quality
The quality of the tuner directly impacts performance gains and engine safety.
Factors Improving Quality:
- Advanced Fuel Mapping: Tuners that offer precise adjustments to timing and fuel delivery provide better, safer power gains.
- Easy-to-Use Interface: A well-designed menu system reduces the chance of you selecting the wrong setting by mistake.
- Regular Updates: Manufacturers should provide free, frequent software updates to support new engine software or improve existing tunes.
Factors Reducing Quality:
- “One-Size-Fits-All” Tunes: If a tuner only offers very basic power bumps without allowing fine-tuning, the gains will likely be minimal, or the tune might run poorly on your specific truck.
- Slow Processing Speed: A slow device makes adjusting settings frustrating.
- Poor Customer Support: If you run into trouble flashing your truck, you need reliable help fast.
User Experience and Use Cases
How you plan to use your Ram 1500 determines the best tuner.
Daily Driving & Fuel Economy:
If you mostly drive to work and want slightly better mileage, select a tuner with a dedicated “Economy” tune. These tunes often adjust shift points and reduce throttle sensitivity for smoother, more efficient cruising.
Towing & Hauling:
Towing demands more torque at lower RPMs. Look for a “Towing” tune that boosts low-end power without creating excessive heat. This helps your Hemi pull heavy loads without straining.
Maximum Performance (Street & Track):
Enthusiasts seeking the biggest horsepower numbers should look for tuners that allow for custom tuning or offer aggressive “93 Octane Performance” tunes. These tunes maximize power but require premium fuel and careful monitoring.
10 Frequently Asked Questions (FAQ) About Ram 1500 Hemi Tuners
Q: Will a tuner void my Ram truck’s factory warranty?
A: Installing a custom tune *can* void the warranty for engine or drivetrain issues if the dealer can prove the tune caused the failure. However, most modern tuners allow you to “return the truck to stock” before visiting the dealer. This often erases the error logs related to tuning.
Q: Can I use the same tuner if I upgrade my 5.7L Hemi to a cold air intake?
A: Yes, usually. Quality tuners allow you to load a new tune that accounts for the added airflow from an intake. If you make major changes (like cams or superchargers), you will need a custom tune.
Q: How much horsepower and torque can I realistically expect to gain?
A: On a stock 2019 Hemi, you can typically see gains ranging from 15 to 30 horsepower and 20 to 35 lb-ft of torque using premium fuel tunes. Bigger gains require more modifications.
Q: Is it difficult to install or flash my truck with a tuner?
A: No, it is generally very simple. You plug the device into the OBD-II port (usually under the steering wheel), follow the on-screen prompts, and select your desired tune. The process usually takes 10 to 20 minutes.
Q: Do I have to run premium fuel (91 or 93 octane) with these tunes?
A: Performance tunes often *require* premium fuel for safe operation and maximum power. Economy tunes are usually safe for 87 octane, but always read the specific instructions for the tune you select.
Q: What is the difference between a “canned tune” and a “custom tune”?
A: Canned tunes are pre-made maps loaded onto the device by the manufacturer. Custom tunes are specifically written by a professional tuner based on your truck’s exact modifications and the fuel available in your area.
Q: Can these tuners help with transmission shift quality?
A: Absolutely. One of the most popular benefits is adjusting the automatic transmission’s shift firmness and timing. This makes the truck feel much sportier and more responsive.
Q: What if I need to quickly switch back to stock settings?
A: All reputable handheld tuners have a “Return to Stock” feature. This overwrites the performance tune with the factory settings before you unplug the device.
Q: Does the tuner affect the truck’s ability to monitor tire pressure (TPMS)?
A: Good tuners let you adjust the TPMS threshold. If you install larger, lower-pressure off-road tires, the tuner prevents the annoying dashboard warning light from coming on.
Q: Are there any fees after I buy the tuner device?
A: Basic canned tunes are included in the purchase price. However, if you want custom tuning files later on, those files are usually purchased separately from a professional tuner.
