Tuning & installation

WHO MAKES YOUR TUNES?

Our tunes are made in-house by people who have worked with Cummins. We build and support the tuning for your truck ourselves.

Why we offer free tuning?

We build our tunes in-house, so we control the tuning costs. Different tunes and tuning adjustments are free with your tuning purchase.

Important Information about the Tune

How does tuning work?

Our tunes are built for real truck owners—people who tow, haul, or drive their rig every day. They're clean, reliable, and built in-house by pros who know what they're doing. No racing nonsense, just solid performance and better fuel economy.

For the 2013-2018 Ram 6.7 Cummins, this means a tune built around eliminating DPF regen cycles, EGR soot buildup, and DEF system faults - including the P20EE SCR efficiency codes that commonly trigger derate on 2013-2018 trucks. Your tune is preloaded on the EZ Lynk device and is calibrated for your specific model year's ECM.

You give us the basics (VIN, make, model, and any mods), and we build a custom tune that fits your truck like a glove. Once it’s in, say goodbye to DEF headaches and warning lights. You’ll be ready to tow with confidence—and it’s all included, no extra fees.


What Does the Device Do?

The tuner plugs into your OBD-II port and loads your custom tune. It also lets you check performance, run diagnostics, and keep your truck dialed in.

Transmission Tuning

Transmission tuning for the 68 RFE is included. This tune optimizes shift points and line pressure specifically for the 68 RFE automatic fitted to your 2013-2018 Ram 2500 or 3500, reducing heat buildup under sustained towing and improving long-term transmission reliability. Better fuel economy under highway and towing conditions is also a consistent outcome.

Horsepower Settings

With the shift-on-the-fly cable included in the bundle, you'll be able to switch between 4 power levels in real time.

EZ Lynk Power Settings:

Level 1: "Stock" No added HP. Ideal for daily driving and towing.

Level 2: +50HP Ideal for fuel economy, reliability, towing and daily driving

Level 3: +100HP Ideal for towing and enthusiastic driving

Level 4: +150HP Ideal for Performance, modifications to truck may be required

Important:

This is just what most customers want. If you’re looking for something different, just let us know on the form we send after your order—we’ll make it happen.

How hard is it to install the kit?

The kit is very easy to install. It usually takes about 4 to 8 hours, depending on how handy you are, but most of our customers do it themselves without any problem. We include clear, step-by-step instructions and give you all the help you need. If you have any questions, we’ll reply quickly so you can finish the job fast. The tuning device takes only about 4 minutes to install since it’s plug and play.
