Single Full Support Pack:

Provides permanent support and continued linkage to our EZ Lynk cloud-based technician profiles for supported Stock Configurations.

Single Limited Support Pack:

Provides access to our EZ Lynk single-tune technician profiles for 4 weeks.

During that period, you can try the available Stock Configuration tune profiles and determine which tune works best for your truck.
