Applications: Most common RAM 1500 engine
Fuel: 87 octane recommended, responds to 93

6.4L 392 HEMI V8

Power: 410 HP / 429 lb-ft (RAM 2500/3500 primarily)
Technology: MDS, VVT
Applications: Heavy-duty models
Strength: More torque for towing

3.0L EcoDiesel V6

Power: 260 HP / 480 lb-ft
Technology: Turbo diesel, DEF system
Efficiency: Best fuel economy in class
Tuning: Excellent torque gains possible

6.2L Supercharged Hellcat (TRX)

Power: 702 HP / 650 lb-ft
Supercharger: 2.4L IHI twin-screw
Application: RAM 1500 TRX
Tuning Potential: Massive, shares Hellcat platform

5.7L HEMI Tuning

Stock Tune Optimization

The 5.7L HEMI in RAM trucks responds well to calibration:

20-30 HP gain through timing and fueling
Improved throttle response
MDS refinement or disable
Better transmission behavior
Tow mode optimization

eTorque Considerations

RAMs with the eTorque mild hybrid system require special attention:

48V motor-generator calibration
Torque fill optimization
Start/stop system tuning
HP Tuners supports eTorque vehicles

Modified 5.7L Gains

CAI + tune: 25-35 HP
Headers + tune: 40-55 HP
Cam swap: 50-80 HP additional
Full bolt-on: 430-460+ WHP achievable

EcoDiesel Tuning

Diesel Tuning Benefits

The 3.0L EcoDiesel has significant tuning headroom:

40-60 HP gain from calibration
80-100+ lb-ft torque increase
Improved fuel economy possible
Better throttle response
Reduced turbo lag

Key Parameters

Boost pressure targets
Injection timing and quantity
Rail pressure calibration
EGR flow (where legal)
DPF regeneration strategy

Emissions Considerations

DEF system calibration available
DPF management important
Emissions equipment modifications for off-road use only
Keep emissions intact for street-driven vehicles

RAM TRX Tuning

Supercharged Potential

The TRX shares the Hellcat powertrain and responds similarly:

Tune only: 750-780 HP
Pulley + tune: 800-850 HP
Full bolt-on: 900+ HP achievable
E85 capable: Additional 80-100 HP on ethanol

TRX-Specific Considerations

4WD system calibration
Transfer case management
Suspension (Bilstein) integration
Off-road mode optimization

Transmission Tuning

ZF 8HP (8-Speed Auto)

Most RAM 1500s use the ZF 8-speed, which is highly tuneable:

Shift firmness adjustment
Shift point optimization
Torque converter lockup strategy
Tow/Haul mode enhancement
Sport mode improvement

TorqueFlite 8 (Diesel)

Diesel-specific shift calibration
Torque handling optimization
Towing shift strategy

HP Tuners Capabilities

PCM Calibration

Full fuel and spark table access
VVT cam timing optimization
MDS control and disable
Speed limiter adjustment
Rev limiter modification
Torque management calibration

Data Logging

Real-time parameter monitoring
Knock detection tracking
AFR verification
Transmission temperature
Boost pressure (diesel/TRX)

Towing Considerations

RAM trucks are workhorses, and tuning must consider towing needs:

Conservative tow mode calibrations available
Transmission behavior crucial for heavy loads
Multiple tune files for switching modes
Cooling system monitoring important
Proper torque management maintains reliability

Common Modifications

Air Intake

Improved airflow and sound
Requires MAF recalibration
5-15 HP gain typical

Exhaust

Headers provide biggest gains
Catback for sound improvement
Mid-pipe delete popular (off-road)

Tire Size Correction

Speedometer calibration for larger tires
Shift point adjustment
TPMS threshold modification

E85 Compatibility

HEMI engines respond excellently to E85:

5.7L: 35-45 HP gain over 93 octane
TRX: 80-100+ HP gain
Flex fuel sensor recommended
Allows running any ethanol blend
