This is not a physical product, these are digital tune files (support packs). You must have an existing EZ-Lynk Auto Agent to link these tunes.
 
By custom tuning a truck, you are given the ability to modify countless parameters to the engine and transmission operation. Wake up your LML Duramax with an Emissions On or Emissions Off Tune from Northspec Built out of Edmonton, Alberta, Canada. When it comes to tuning, we only sell what we run ourselves.
 
How does our custom tuning work?
Step 1. You choose your tune by truck year and the device you are using, make sure to fill out all modifications done!
Step 2. We write writes an optimized tune to specifically suit your truck and modifications. These can be customized to suit any setup, whether it's a twin-turbo race truck or a daily driver tow rig
Step 3. We contact you with instructions and your tune (we try our best to have this ready within 1 business day!)
 
With EZ-Lynk, we have the ability to link you up on our end, so the next time you connect to your truck, you will see our email as a new technician and the files will be pushed to you automatically.
 
Power Levels typically range from 0-180HP. Higher Power levels can be written with the proper supporting modifications. Different power levels can be written under request and/or depending on modifications to the vehicle. As all tune files are custom; this will give you a general idea of what you could or can get:
 
Level 1 30 HP
Level 2 60 HP
Level 3 90 HP
Level 4 120 HP
Level 5 150-180 HP
 
TCM Tuning is optional, however, recommended.
 
All Duramax 5 stage tuning is SOTF.
