EZ LYNK AutoAgent 2 Tuner with Custom Tuning by GDP

IMPORTANT: As tuning is customized to your vehicle, it will take 24-48 hours (2 business days) after connecting to your truck for GDP to deliver the tuning files to your EZ LYNK device. Tuner REQUIRES an iOS, Android or EZ LYNK Compatible Monitor (not included) to download and apply tuning.

  • The Future of Diesel Tuning Delivered Now: The revolutionary EZ LYNK AutoAgent 2 is changing the way modern vehicles are tuned. Using cloud-based tuning & diagnostic delivery, wireless access point technology and the expert tuners at GDP, the EZ LYNK from GDP ensures that the provided tuning is perfectly suited to your truck.
  • Power and Performance to Suit Your Needs: The GDP Tuning EZ LYNK can be configured in a variety of different ways to suit the specific operational requirements and the needs of your truck based on your current modifications. Whether you have a daily driver, a towing workhorse or a race truck, GDP provides a choice of tuning that fits you. Each unit includes "Switch-on-the-Fly" (SOTF) tuning with 4 custom power tunes and a stock power tune. A switch is REQUIRED for "on-the-fly" tune changing. See "Power Levels" for details.
  • Modern Simplicity: The EZ LYNK AutoAgent connects to your truck through the OBDII port and broadcasts a WiFi Access Point (WAP) which allows a wireless connection to the vehicle using any iOS/Android device or the GDP EZ LYNK compatible monitor. By launching the free EZ LYNK application on your device, engine data is seamlessly streamed and updated in real time on your screen.
  • The Power of Knowledge: End users can conveniently share data-logs and other vehicle information to any technician with the touch of a finger without even leaving the driver seat. Datalogs can be quickly started and stopped from the main gauge display screen and bookmarks can be added to draw interest to specific points of a datalog if desired. A fully customizable user interface allows the end-user to create a gauge interface that suits their particular needs. Technicians can also create default PID configurations that are automatically loaded during a re-flash procedure to further assist in the troubleshooting and diagnostic process.
  • How It Works: Because this tuning is custom made for your specific needs and modifications, the GDP EZ LYNK will not come pre-loaded with tuning. Upon receiving the product, the EZ LYNK will need to be installed in your truck. Once the tuner is installed, GDP will be able to recognize the unit on their cloud based software. After this, you will send a profile to GDP Tuning that contains information about your truck such as tire size, injectors, and other modifications. GDP Tuning will then build the tuning specifically for your truck within 48 hours (2 business days).

JAMO 5" Stainless Steel DPF, DEF & CAT Delete Exhaust System with Polished Tip

IMPORTANT: This Delete Exhaust is NOT suitable for Chassis Cab trucks. These kits will only fit LML models equipped with the OEM style V-band Clamp off the turbo direct pipe! If you do not have a V-band Clamp, please choose parts for 2015.5-16.

JAMO's Stainless Race Delete Exhaust Systems replace the entire exhaust from the Downpipe Back with 5" 409 Stainless Steel straight pipe. They generally do not require welding or modification and install easily using OEM mounts and hanger locations. Better still, JAMO includes a polished 304 Stainless Steel tip with every exhaust. JAMO is the new kid on the block, however they manufacture an exceptional stainless steel exhaust system at a lower price than Flo~Pro and aFe.

  • THE STEEL: 5" Mandrel Bent 409 Stainless Steel Tubing
  • HAVE A TIP: Every JAMO Race Delete Exhaust System includes a polished 304 Stainless Steel tip that easily bolts on for a stylish finish.
  • OPTIONAL MUFFLER: The optional Stainless Steel 30" x 6" free-flowing muffler keeps the power but reduces the sound.
  • EASE OF INSTALLATION: Installs simply and securely using OEM mounts and hangers ensuring your exhaust will stay put once installed. The kit includes all the hardware required to get the job done.
  • MULTIPLE BENEFITS: While a free flowing delete exhaust will increase HP and torque performance, it also reduces EGTs and eliminates "Regen" resulting in a more efficient truck, too.
