THIS EZ LYNK PACKAGE IS FOR E46 ECM TRUCKS ONLY.
If you are unsure which ECM your truck has, contact us with your 17-digit VIN before ordering.
2022 TRUCKS – PLEASE VERIFY BEFORE ORDERING
GM transitioned the Silverado and Sierra to the refreshed platform during the 2022 model year.
The refreshed 2022.5+ trucks use a different controller and are not compatible with this product.
HOW TO IDENTIFY A REFRESH TRUCK
One of the easiest ways to tell is by looking at your center radio/display.
Large newer-style center screen = 2022.5+ Refresh
Older-style center screen = Pre-refresh / Non-refresh
For 2022 trucks, the 12th digit of the VIN can also help identify the build:
-
4 or lower = Pre-refresh / Non-refresh
-
5 or higher = Refresh / 2022.5+
If there is any question about compatibility, send us your VIN before purchasing.
STAGE 1 | THE TRICERATOPS
BASIC PACKAGE
The Triceratops is our simplest and most affordable LM2 package.
It is designed for customers who want the basic components needed for the setup without paying for the additional hardware, tuning options, and long-term support included with Stage 2 and Stage 3.
STAGE 1 INCLUDES:
-
EZ LYNK AutoAgent

4-Week Tuning Access & Support Package
(FREE Dyno Diesels 3-Tune Package) -
4-Piece CANbus Plug Kit
-
LM2 DPF / DEF Delete Pipe

EGR Unplug (Physical EGR removal is NOT required)
STAGE 2 | THE VELOCIRAPTOR
BEST BUDGET VALUE
The Velociraptor is designed for customers who want a more complete setup but still need to keep the overall package price within a budget.
Stage 2 keeps the 4-week tuning access and support package from Stage 1 but upgrades the included tuning to the FREE CCS 7-Tune Package.
It also adds the complete LM2 EGR Delete Kit, allowing physical removal of the applicable factory EGR components.
STAGE 2 INCLUDES:
-
EZ LYNK AutoAgent
-
4-Week Tuning Access & Support Package
FREE CCS 7-Tune Package -
4-Piece CANbus Plug Kit

🦖 STAGE 3 | THE T-REX
ULTIMATE PACKAGE | DYNO DIESELS #1 RECOMMENDATION
If you want the package we recommend most, choose Stage 3 – The T-REX.
The T-REX is built for customers who want to purchase the complete setup from the beginning instead of piecing together upgrades later.
Most importantly, Stage 3 upgrades you from the limited 4-week tuning support included with Stage 1 and Stage 2 to our LIFETIME TUNING SUPPORT PACKAGE.
You also receive the FREE CCS 7-Tune Package, complete EGR delete hardware, CANbus plug kit, DPF/DEF delete pipe, and an S&B Cold Air Intake.
STAGE 3 INCLUDES:
-
EZ LYNK AutoAgent
-
LIFETIME TUNING SUPPORT PACKAGE
-
FREE CCS 7-Tune Package
-
4-Piece CANbus Plug Kit
-
LM2 DPF / DEF Delete Pipe
-
Complete LM2 EGR Delete Kit
-
S&B Cold Air Intake
WHY WE RECOMMEND STAGE 3
The major advantage is Lifetime Tuning Support.
Stage 1 and Stage 2 include a 4-week tuning support window.
Stage 3 gives you the long-term support package.
Diesel builds can change over time. You may later change supporting modifications, replace components, install additional performance parts, or require tuning assistance.
Choosing Stage 3 means you're purchasing a package designed around the truck's long-term tuning needs, not simply getting it set up today.
★ BEST OVERALL PACKAGE
★ BEST LONG-TERM VALUE
★ LIFETIME TUNING SUPPORT
If your budget allows it, Stage 3 is the package we recommend.
