Best Tuner For Dodge Challenger: Compare HEMI and OBD2 Options

#1 · Best Overall

1. DiabloSport 8320 Intune i3

• Weight: 0.27 g
• Warranty Description: Warranty

Best for: 2015–17 HEMI PCM-swap option.

Why it ranks #1: Lists 2015–2017 Challenger fitment with 5.7L or 6.4L HEMI engines and includes dyno-tested performance tunes through an OBD-II connection.

The PCM Swap designation and listed 2015–2017 Challenger coverage distinguish the DiabloSport 8320 inTune i3 for owners of 5.7L or 6.4L HEMI V8 models. Dyno-tested tunes and a touchscreen Easy Tune interface put performance adjustments within a direct OBD-II workflow.

Its direct OBD-II connection and responsive touchscreen support handheld parameter adjustments, while Easy Tune mode offers a more guided tuning workflow. Dyno-tested calibrations target horsepower, torque, throttle response, drivability, and fuel economy, so the device addresses several performance priorities. The supplied compatibility identifies 2015–2017 Challenger models with 5.7L or 6.4L HEMI V8 engines and names a PCM Swap version; buyers should keep that stated year and engine range in view.

Skip it if you own a 2008–2014 Challenger with a listed V8; the DiabloSport 9300 Trinity 2 EX specifies those years and engine options.

This suits 2015–2017 Challenger owners with the listed 5.7L or 6.4L HEMI seeking touchscreen performance tuning. Its stated coverage does not establish fit for newer model years or other engines.

#2 · Best Settings Control

2. Z Automotive Tazer

• Warranty Description: 90 Day Warranty

Best for: Challenger settings customization.

Why it ranks #2: Fits 2015–2023 Challengers and adjusts over 70 features; 2018-and-newer vehicles require a security gateway bypass module.

More than 70 adjustable features make the Z Automotive Tazer a settings-focused choice for 2015–2023 Dodge Challenger owners. Its OBD2 plug-in format gives access to vehicle settings, live settings, and non-menu live functions, letting owners change supported behavior through a device made for the listed vehicle range.

The Tazer connects through the diagnostic OBD2 port, so installation is a plug-in process rather than a hood-side procedure. Its vehicle and live-setting adjustments give owners a way to customize supported functions, while non-menu live functions extend its role beyond a static settings tool. Challenger coverage spans 2015–2023, but 2018-and-newer models require a Double Bypass or Security Gateway Bypass Module for the Tazer to function; that requirement affects parts planning and setup.

Skip it if you want engine performance calibrations; the DiabloSport 8300 inTune i3 lists dyno-tested performance tunes for supported Challengers.

For Challenger owners prioritizing vehicle-setting changes and live functions, the Tazer offers a direct OBD2 workflow. Check the listed year range, and account for the required bypass module on 2018-and-newer models before choosing it.

#3 · Broad HEMI Coverage

3. DiabloSport 8345 Intune i3

• Weight: 9.9 oz

Best for: HEMI tune adjustments.

Why it ranks #3: Lists Challenger compatibility for 2004–2014 5.7L, 6.1L, or 6.4L HEMI models and provides touchscreen tuning with PCM swap.

Dyno-tested performance tunes are the core draw of the DiabloSport 8345 inTune i3 Platinum, aimed at listed Ram, Charger, and 300 models with 5.7L, 6.1L, or 6.4L HEMI V8 engines. Its touchscreen and Easy Tune mode let owners adjust parameters without lifting the hood.

The direct OBD-II connection supports a handheld tuning workflow, while Easy Tune mode and a responsive touchscreen simplify parameter adjustments. Its performance calibrations target horsepower, torque, throttle response, drivability, and fuel economy, giving HEMI owners several tuning goals in one device. Compatibility is specifically listed for 2004–2014 Ram 1500, Charger, and 300 applications with the named HEMI engines, so Challenger shoppers should note that the supplied fitment does not list Challenger models.

Skip it if you need listed Challenger fitment; the DiabloSport 8300 inTune i3 names Challenger models with 5.7L HEMI V8 coverage.

This suits a buyer with a listed 2004–2014 Charger or 300 HEMI seeking handheld performance calibration. For a Challenger, the supplied compatibility information does not establish fit, so choose based on confirmed vehicle coverage.

#4 · Touchscreen Monitor

4. DiabloSport 9300 Trinity 2 EX

• Weight: 1.5 lb

Best for: Touchscreen tuning and monitoring.

Why it ranks #4: Supports 2008–2014 Challenger V8 applications, including 5.7L, 6.1L, and 6.4L engines, with a touchscreen interface.

A touchscreen pairs tuning and monitoring in the DiabloSport 9300 Trinity 2 EX, giving compatible HEMI Challenger owners one interface for performance calibrations and supported vehicle settings. Its listed coverage includes 2008–2014 Challenger models with 5.7L, 6.1L, or 6.4L V8 engines.

The Trinity 2 EX is described as both a tuner and monitor, so its touchscreen can serve drivers who want calibration access alongside vehicle information. Performance calibrations target horsepower, torque, throttle response, and drivability, while supported settings add a customization workflow. The supplied Challenger compatibility covers 2008–2014 models and specifies three V8 engine options; that makes the fitment boundary central for shoppers with newer cars or a different engine configuration.

Skip it if you own a 2015–2017 HEMI Challenger; the DiabloSport 8320 inTune i3 lists those model years.

Choose the Trinity 2 EX if your Challenger falls within the listed 2008–2014 V8 coverage and you value tuning plus monitoring on a touchscreen. Its stated Challenger range does not include 2015-and-newer models.

#5

5. DiabloSport 8300 Intune i3

• Weight: 9.5 oz

Best for: Older 5.7L Challenger tuning.

Why it ranks #5: Names 2003–2014 Challenger fitment with a 5.7L HEMI and offers dyno-tested tunes, though its stated engine coverage is narrower.

Dyno-tested performance tunes for 5.7L HEMI V8 applications make the DiabloSport 8300 inTune i3 a focused option for 2003–2014 Challenger owners. Its Easy Tune mode and responsive touchscreen provide a direct way to adjust supported vehicle parameters through a direct OBD-II connection.

Its performance tunes target horsepower, torque, throttle response, drivability, and fuel economy, giving owners multiple calibration goals. The supplied Challenger fitment is specifically 2003–2014 with a 5.7L HEMI V8; shoppers with other engines or later model years should treat that stated coverage as the relevant limit.

Skip it if you have a 2015–2017 Challenger with a 5.7L or 6.4L HEMI; the DiabloSport 8320 inTune i3 lists that fitment.

The 8300 suits owners of listed 2003–2014 5.7L HEMI Challengers seeking handheld performance adjustments. Its stated coverage does not extend to later years or other Challenger engine options.

#6

6. Bully Dog 40430 Hemi Plus

• Weight: 2.08 oz

Best for: 2011–12 HEMI monitoring.

Why it ranks #6: Its description identifies the Hemi Plus for 2011–2012 HEMI vehicles and lists settings such as door alerts and daytime running lamps.

Audible alerts for automated engine protection distinguish the Bully Dog 40430 Hemi Plus Gauge Tuner for 2011–12 Hemi applications. Its multi-function vehicle monitoring is paired with driver-facing convenience settings, including lock sounds, hazard flashes, daytime running lamps, and door and seatbelt alerts.

The monitoring and automated engine-protection functions make this more than a list of convenience toggles: audible alerts can notify the driver, while the gauge-tuner format supports vehicle monitoring. The listed settings also let owners enable a horn or hazard flash on lock and adjust daytime running lamps, door alerts, and the seatbelt minder. The supplied description identifies it for 2011–12 Hemi vehicles, making that narrow application range an important fit boundary.

Skip it if you need listed 2015–2017 Challenger performance tuning; the DiabloSport 8320 inTune i3 specifies those HEMI Challenger years.

This is a fit for owners of listed 2011–12 Hemi vehicles who want monitoring, audible protection alerts, and select convenience settings. Its supplied application is narrow, so later Challenger owners should look elsewhere.

#7 · Street-Legal Claim

7. Bully Dog 40410 GT Gas Tuner

• Weight: 16 oz
• Warranty Description: Bully Dog Technologies warrants that the…

Best for: Street-legal display and tuning.

Why it ranks #7: Lists broad select-Dodge application coverage and claims 50-state emissions compliance, but gives no Challenger model-year or engine range.

A heads-up display showing more than 15 performance parameters gives the Bully Dog 40410 GT Gas Tuner a dashboard-monitoring focus alongside its 50-state-compliant tunes. The broad listed make coverage includes select Dodge and Chrysler applications, while the supplied facts caution that support varies by vehicle.

The dynamic LCD display presents more than 15 performance parameters at a glance, helping drivers keep vehicle information visible during a drive. Its dyno-proven tunes are described as adding power, torque, and fuel economy, and the 50-state compliance addresses emissions requirements. The supplied coverage spans select makes and models rather than every Dodge, so the display and tuning benefits depend on an application that supports the vehicle and its parameters.

Skip it if you need specified 2015–2017 HEMI Challenger coverage; the DiabloSport 8320 inTune i3 lists those years and engines.

The GT Gas Tuner suits drivers seeking a parameter display and street-legal tuning across supported applications. Dodge Challenger owners should weigh the broad-but-selective fitment against the specifically listed vehicle coverage they need.

#8

8. ACCEL 49505 SuperTuner

• Weight: 9.9 oz

Best for: Adjustments and diagnostic checks.

Why it ranks #8: Offers adjustments and diagnostic functions, but the supplied information does not specify Dodge Challenger compatibility or applicable model years.

Shift-point and firmness adjustment gives the ACCEL 49505 SuperTuner a control-oriented role, joined by tire-size and axle-gear-ratio adjustments. Its color screen and diagnostic functions support a handheld workflow for owners who want to change supported parameters and read or clear trouble codes.

The HD 2.8-inch color screen provides an interface for modifications, while PC software enables internet updating.

The SuperTuner can also read and clear trouble codes with explanations, adding a diagnostic task to its tuning workflow. Supplied details do not specify Challenger model-year or engine coverage, so its fitment should be established before relying on these functions.

Skip it if you need named Challenger year and engine coverage; the DiabloSport 9300 Trinity 2 EX lists specific Challenger years and V8 options.

This fits buyers prioritizing adjustment controls and diagnostic code handling in one tuner. Challenger shoppers should treat the supplied fitment details as a boundary: they do not name supported model years or engines.
