What We Do
Our Services
Specialized Stellantis electronics services for Dodge, Jeep, Chrysler, and Ram. Mail-in available nationwide.
01
Dealer-Level Stellantis Programming
PCM, BCM, TCM, and more — programmed with the same factory software the dealer uses. Same result, none of the dealership pricing.
Info →
02
VIN Changes
Engine swap, module swap, whatever the reason — we get the VIN updated correctly in your control modules. Proof of ownership required before we start.
Info →
03
Module Unlocking
Getting a tune done or building something custom? We'll unlock the PCM so your tuner has full access. Covers Dodge, Jeep, Chrysler, and Ram.
Info →
04
IMMO Sync
Car won't start after a PCM, BCM, or RFHUB swap? That's almost always an immobilizer sync issue — and it's what we fix.
Info →
05
Used Module Programming
Found a module at the salvage yard? Send it our way. We'll tie it to your VIN and get it configured so it just works.
Info →
06
Airbag Module Reset
A deployed airbag module locks itself out and stores the crash data. Most of the time it doesn't need to be replaced — just reset back to factory.
Info →
07
Mileage Reset / Correction
New cluster, repaired cluster — either way the mileage needs to match the vehicle. We calibrate it correctly for your records.
Info →
08
SRT Page Install
0-60 times, G-force, horsepower readouts, and SRT Drive Modes — right on your Uconnect screen. Available on compatible Dodge, Chrysler & Jeep models. One-time $75.
Info →
09
File Services
Already have a PCM unlock, IMMO resync, calibration, or VIN file you need worked on? Send it over and we'll handle it remotely — no shipping required.
Info →
10
Performance Tuning
Custom ECU tunes for HEMI, EcoDiesel, and Pentastar platforms — plus late-model muscle, exotic, and foreign vehicles. Horsepower & torque gains, throttle response, shift firmness, and more. Pricing depends on platform and goals.

Not Just Mopar
Dodge, Jeep, Chrysler & Ram Are Our Specialty — Not Our Limit
We do plenty of cloning, unlocking, and programming work on other makes too. Got something that's not on the list? Send us the details and we'll let you know if we can help — most of the time we can.
