NGC3/4/4A TUNER - 2004 - 2011 CHRYSLER/DODGE/JEEP/RAM
NGC4 TUNER
Tune Your Own Vehicle at Home — or Request a Custom Tune
2004–2011 Dodge · Chrysler · Ram · Jeep — Chrysler NGC3 / NGC4 / NGC4A PCM
The NGC4 Tuner by Custom Tunez puts real ECU tuning in your own hands. Read your vehicle, adjust supported parameters, and flash it back — all yourself, from your driveway, through the OBD port. No ECU swap. No mail-in. No core return. No tuning shop.
Just the cable and the software — you're in control.
Two ways to tune:
Do it yourself — Use the built-in tools to adjust rev limiter, speed limiter, exhaust sound, MDS and more, then flash your own calibration. Change it as often as you like on your licensed vehicle.
Request a Custom Tune — Want a professionally built calibration? Read your vehicle through the app and submit it to Custom Tunez with your vehicle and modification details — we'll build a tune for your setup and send it back to flash yourself.
Either way, your original calibration is always backed up, so you can return to stock anytime.
Designed for supported 3.5L V6, 4.7L V8, 5.7L HEMI and 6.1L HEMI applications.
What You Can Do
READ YOUR ECU
Read the supported PCM calibration directly through the vehicle's OBD connection.
Each read is integrity-checked before being accepted, helping prevent an incomplete or corrupted read from being used for a subsequent flash.
Your original calibration is automatically retained as a backup.
ADJUST SUPPORTED VEHICLE PARAMETERS — YOURSELF
An easy-to-use interface gives you access to supported calibration parameters — no traditional binary editing software, no tuning background required.
Available functions may include:
Rev Limiter — Adjust supported Drive, Park/Neutral, and (where applicable) auto-stick engine-speed limits
Speed Limiter — Adjust the vehicle speed-limiter setting where permitted
Exhaust Sound / Burble — Adjust supported exhaust-sound characteristics — pops, pops+, burble and duration — where permitted
MDS / Cylinder Deactivation — Configure supported cylinder-deactivation operation on equipped 5.7L HEMI applications where legally permitted
Additional Calibration Options — Availability depends on vehicle, application, and intended use
Not every feature is available for every vehicle or jurisdiction.
Adjustments can be made as often as you like on your licensed vehicle.
SCAN & CLEAR DIAGNOSTIC TROUBLE CODES
Run a diagnostic scan directly through the application to see any stored trouble codes on the supported PCM.
Review what's present, then clear stored codes once the underlying condition has been addressed — no separate scan tool or shop visit required.
Diagnostic scanning and clearing is intended for legitimate diagnostic and maintenance purposes. Clearing a stored code does not repair the underlying condition, and codes will return if the condition is still present.
FLASH YOUR CALIBRATION
Write supported calibrations directly to the NGC PCM through the included flashing hardware.
The platform verifies compatible ECU information and calibration data before beginning supported programming operations.
STOCK BACKUP & RESTORE
Your original PCM calibration is retained when the vehicle is first read.
Need to return to the original calibration? Select the original backup and flash it back to the PCM — anytime, yourself.
INSTANT ECU IDENTIFICATION
Quickly identify supported ECU information including:
VIN · Calibration ID · ECU Type · Serial Number · Part Number
Know exactly what controller you're working with before making changes.
REQUEST A CUSTOM TUNE
Prefer a professionally developed calibration, or pushing bigger mods?
Read the vehicle through the NGC4 Tuner and submit the calibration to Custom Tunez along with information about your vehicle and modifications.
Custom Tunez can provide a calibration appropriate for the supported vehicle and intended application, subject to applicable emissions and vehicle regulations — and you flash it yourself with the same app.
COMPATIBILITY
Designed for supported 2004–2011 Dodge, Chrysler, Ram and Jeep vehicles equipped with the Chrysler NGC3, NGC4 or NGC4A PCM, including selected:
3.5L V6
4.7L V8
5.7L HEMI V8
6.1L HEMI V8

Other supported NGC vehicles
Compatibility is determined by PCM type (NGC3 / NGC4 / NGC4A) and calibration, not simply vehicle year/model.
ECU ACCESS REQUIREMENTS
No unlock service required. Supported 2004–2011 NGC applications are programmed directly through the vehicle's OBD connection — there is no mail-in unlock, no ECU swap, and no security-gateway bypass hardware needed.
Contact Custom Tunez with your year, make, model, and engine if you're unsure whether your vehicle is supported.

IMPORTANT EMISSIONS & LEGAL NOTICE
The NGC4 Tuner is a vehicle calibration and programming platform. It is not intended to bypass, defeat, disable, or render inoperative any emissions-control system required by federal, state, provincial, or local law.
Custom Tunez does not authorize the removal or disabling of catalytic converters, oxygen-sensor monitoring, evaporative-emissions systems, emissions-related diagnostic functions, or other legally required emissions-control equipment.
Users are responsible for ensuring that vehicle modifications and calibrations comply with all laws and regulations applicable to the vehicle and its location.
Certain calibration features may be restricted to applications where their use is lawful.
We ask for your VIN up front so the calibration is built for your exact car — not a generic file.
Before you order
Not sure this is the right file for your car? Ask first — we would rather talk you out of the wrong product than refund it.
Your factory file is archived
Going back to stock is always one flash away.
Built for your VIN
That is why we ask for it at checkout — the calibration is written for your exact engine and software version, not a generic map.
Support after the sale
Installation help by phone, and an engineer on the line for remote flashes.
Not sure which one you need?
Tell us the year, model and what's already on the car. We'll point you at the right product in one call.
