Why EZ Lynk Is The Way To Go For Cummins 6.7L Tuning

Posted by Ben Lawson on Nov 10, 2022 10:57:52 AM

The EZ Lynk 2.0 has quickly become one of the post popular tuning devices on the market and its easy to see why with all of its features. Now with the introduction of the Auto Agent 3.0 combined with custom tuning from Calibrated Power you can turn your 2013 to 2021 6.7L Cummins into the ultimate daily driver! 

 Not only can the ECM be tuned withe the EZ Lynk devices but the TCM of the 68FE transmission can be tuned as well. This is huge because it means you'll be able to put down more of the power you're able to make to the wheels. This lets you go from a performance tune where you're only able to access 60-70 extra horsepower at the wheels. To a proper +100hp tune with transmission adjustments that improve the lock-up of the torque converter and shift scheduling to enhance power delivery though out the entire usable rev range.  All with the stock emissions system fully intact. Calibrated Power actually offers a range of tuning options to go along with your EZ Lynk tuner and they can vary based on whether your truck has a built transmission or not. Here's how much power you can expect:

Stock Transmission Tunes:

1. Heavy Tow: +20HP
2. Light Tow:  +40HP
3. Street:   +80HP
4. Race.         :     +100HP

Built Transmission Tunes:

1. Heavy Tow : +40HP
2. Light Tow   : +60HP
3. Street.        : +110HP
4. Race          : +160HP

You've probably read on forums that it's a good idea to delete the emissions system on your Cummins 6.7L to help improve fuel economy and make more power. However, tuning can do all of this for you and you won't have to sacrifice your factory emissions system to do so. The emissions equipment has evolved over years with the benefit of GOOD tuning to help make your truck drive the way you want it to. Plus emissions-intact tuning for the 6.7L will provide you with such a substantial improvement to power and drive-ability, mainly thanks to the included transmission tuning, that you won't feel any need to remove your emissions equipment after it's installed.

Here are five good reasons to keep your factory emissions system installed:
  • Trucks w/ emissions systems hold better resale valuable
  • No cost of having to remove or replace your exhaust system/potential fines
  • Quiet exhaust
  • No smoke from the tailpipe
  • No smelling worse

Auto Agent 3 (2)
The main difference that you'll find between the new Auto agent 3.0 and its predecessor the Auto agent 2.0 is mainly their form factor. While a few software upgrades have been built in like the ability to code things such tire size for speedometer correction directly to the ECM. The main advantage you're getting is the new size and shape that should allow you to keep your auto agent plugged into your OBDII port at all times. Letting you easily and constantly measure engine data. Being able to do this is what makes the EZ Lynk devices so much better than other devices on the market and this new device improves on that functionality.
