Description
Dodge Durango 5.7L HEMI HP Tuners Stage 1 Custom Remote Tune — Stock & Bolt-Ons
A fully custom HP Tuners calibration for your Dodge Durango 5.7L HEMI 5.7L HEMI V8, written by N2 Speed for stock vehicles and builds with minor bolt-ons — exhaust, headers, cold air intake or a throttle body. This is not a canned file: we build the calibration around your VIN, your modification list and the fuel you actually run, then refine it from your data logs.
Who This Stage 1 Tune Is For
Stage 1 suits stock vehicles and builds with minor bolt-ons — exhaust, headers, cold air intake or a throttle body. If your build sits between two stages, email your mod list to sales@n2speed.com before ordering and we will tell you which package to buy.
Expected Gains
Typical results: 20-30 hp and 25-35 lb-ft at the crank on 93 octane, plus sharper tow and shift behaviour. Gains vary with modifications, fuel quality, altitude and ambient temperature. We calibrate for reliable, repeatable power — not a dyno number you cannot drive.
What We Tune
- Hemi spark and fuel tables, mds cylinder deactivation strategy, torque management, throttle mapping, tow/haul logic, torque converter lockup and 5-speed or zf8hp shift scheduling
- Wide-open-throttle and part-throttle fueling
- Ignition timing with knock-safe margins for your fuel
- Throttle mapping and torque management limits
- Transmission shift points, firmness, tow/haul logic and torque limiting where applicable
- Optional MDS removal, speed limiter removal and drive mode tweaks
Vehicle Fitment
2004-2024 Dodge Durango 5.7L HEMI, including R/T, Citadel and Tow N Go. 2015 and newer Durangos ship with a locked PCM and need our mail-in unlock service before HP Tuners can write to them — send your VIN and we will confirm.
HP Tuners Credits This Vehicle Needs
Total Credits Needed
Credits are how HP Tuners licenses each vehicle. They load onto your MPVI4 and are spent once, the first time the module is read. Adding transmission tuning means a second module is licensed, so the credit total goes up — the options above already include both.
- Engine Only — 2004-2024: 2 Universal Credits
- Engine and Transmission — 2014-2024 ZF8HP 8-speed: 6 Universal Credits
Credit requirements are set by HP Tuners and can change with model year. If your Durango is not listed exactly, send your VIN to sales@n2speed.com and we will confirm before you buy anything.
What You Need
- HP Tuners MPVI4 with Pro Feature Set or another HP Tuners interface, plus credits for your vehicle
- Windows laptop with HP Tuners VCM Suite installed
- Ability to record and send data logs
- Wideband air/fuel gauge — recommended for this stage
What's Included
- One custom calibration built for your 5.7L HEMI V8 and modification list

Locked PCM?
Stellantis locks the PCM on 2015 and newer vehicles. If your Durango cannot be written through the OBD-II port, we offer a mail-in Dodge, RAM & Jeep PCM unlock service and Dodge PCM bench tuning service. Send your VIN to sales@n2speed.com and we will confirm before you buy.
