About our 5 tunes
Heavy Tow Tune
For those towing from 8,000 lbs up to GVWR (Gross Vehicle Weight Rating). +0 RWHP, +55 ft-lbs torque over factory. A wider torque curve assists heavy loads, keeps a balance of sport driving & functionality, and drops exhaust temps up to 100°F under full load.
Light Tow Tune
For those towing any load up to 8,000 lbs. +30 RWHP, +115 ft-lbs torque over factory. Designed for the weekend tower: boats, small tractors, and more. Unhook and enjoy a sportier drive.
Sport Economy Tune
Fun “unloaded” daily driving around town and on the highway. +50 RWHP, +160 ft-lbs torque over factory. Impress your friends and put a smile on your face.
Hot Street Tune
The bridge between Sport Economy and Race: a little more aggressive, but still behaves nicely on the street. +100 RWHP, +235 ft-lbs torque over factory.
Race / Max Effort Tune
Maxes out the factory turbo. +150 RWHP, +385 ft-lbs torque over factory. At this level we highly recommend a WC Fab turbo mouthpiece, a cold air intake, and a FASS fuel system. TCM tuning is recommended for this level.
Additional details
ATTENTION: No transmission tuning is included unless you select it. If you do, you’ll need to send your stock TCM file to Empire’s engineers to build your TCM tune file. Please be patient. We’ll walk you through the entire process, so no worries, you’ll be in good hands!
EGR Delete Kit
Factory cooler setups recirculate soot and harmful gasses through your engine, causing build-up and clogs that lead to lost performance and proven mechanical issues. Cooler upgrade kits remove those concerns from the equation. Components install with an exact fit for a longer-lasting, better-running truck: less turbo lag for better throttle response, cooler engine temps, less weight, and a cleaner engine bay. Proudly made in Canada.
DPF/DEF Exhaust Systems
The exhaust is a DPF race pipe or a full 4- or 5-inch system (depending on what is selected). It replaces your old exhaust from the down pipe back, removing DPF emissions components, and is built to work in conjunction with the tuning.

Package was well out together. Easy to follow step by step instruction.
I bought the complete delete kit and auto agent 3 tune. Absolutely amazing products with extremely precise fit! My 2019 gmc 2500 has never ran like it does now. I started with 15.9 mpg and now I’m mid 20’s. The customer service was matchless answering any question I through at them.
Fast shipping, received in a few days. Fast and easy tuning process had my tunes quickly and installed with no issues glad I chose ezlynk over hp, the truck has been running well for a week now. All hard parts up top fit well, wish they were black but oh well. Downpipe fit in the turbo like it should and looks to be good quality. Only issue was with the exhaust the second hanger past the trans cross member was welded on too far back and was unusable so that piece of pipe hits the crossmember and vibrates. One other was the downpipe and beginning of the exhaust didn’t seal evenly like it should no matter how I moved it it just wouldn’t seal evenly it’s sealed just lop sided. Those were the only 2 issues to address maybe they will fix it in the future. Everything else went on well with no issues.
Zero issues quick and easy install see a huge difference in the truck would definitely use Empire Diesel again!
Great communication from the start! The order came quickly and tech support the whole time during installation
Great customer service great product. Issue with shipping a box but the corrected immediately!
2022 2500 AT4 duramax and this was a pretty forward install. Still working onsome minor fixes but overallit went great.
Easy tune. Fairly straightforward install. Product came right away and packaged great
Empire Diesels has the best customer service from anywhere I’ve gotten truck parts. Staff are all very knowledgeable and support is there for any situation! My truck runs so much better and gets 5 mpg better fuel mileage with way more power! Highly recommend this team and there kit
Great product everything fit nicely the tuning was very simple. instructions would’ve been helpful
Great products, excellent tech support. The performance of the truck exceeded my expectations by far. The only issue I experienced was the shipping company misplaced a 74lb box of exhaust. Empire was quick to remedy the issue. Install was easy. Would absolutely order from them again.
The truck is way more responsive, especially when towing uphill. Install was easier than I thought, and everything worked perfectly. Couldn’t ask for better results.
Hands down best diesel performance shop out there
Great company, solid parts and unbeatable tunes. Have used them in the past, currently and will in the future!
Empire Diesels Sure has a Great staff. Was a real pleasure, They are very knowledgeable and super helpful! Would highly recommend buying your off road Kits here you won't be disappointed.
Love it!
The installation process was easy to follow, and I had it all set up in just a couple of hours. What really blew me away was the customer service. I had a question about loading the tune late Saturday afternoon, and they got back to me within the hour. ON A WEEKEND. I was seriously impressed. They gave me clear instructions, and I was able to fix my issue right away. My truck has been running stronger, smoother, and with way better throttle response since. This kit is worth every penny!
Easy process overall. The parts were high quality, and installation wasn’t too bad. My truck’s performance is night and day compared to before. Highly recommend this!
Very easy and simple job follow the instructions the send you in the emails and it will go off with out a hitch. All parts fit good and are well made. Thanks again my truck runs and sounds amazing!
Empire Diesels killed it. You won’t be disappointed. The delete kit was great, went in super easy and changes the truck completely.
Easy to install, 5inch sounds amazing. Works flawlessly. I have to say some of the best customer service I’ve ever worked with. Had a few Questions and they had them Answered ASAP And it was on the Weekend Empire went above and beyond I was super impressed Would recommend Empire Diesels for any parts you are needing. 🤙💯💯💯
Amazing kit with outstanding directions. Everything fit & went well, love it and Couldn’t be happier!!!!!
I’ve built and tuned a lot of trucks over the years, but Empire Diesel just raised the bar. I picked up their 2019–2023 6.6L L5P Duramax EZ Lynk AutoAgent 3 All-In-One Custom Kit with the Lifetime Support Package, and it’s honestly the smoothest, most complete setup I’ve ever installed.
From the moment I ordered, the communication and support were first-class. They sent clear instructions, walked me through setup, and had my custom tunes loaded faster than I expected. The EZ Lynk paired flawlessly — within minutes my truck was linked, tuned, and ready to roll.
The difference was night and day. Throttle response is crisp, shifts are perfectly dialed in, and power delivery is smooth across every mode. The 5-level switch-on-the-fly tunes make it feel like I’ve got five different trucks in one — from towing to all-out performance, each map is spot-on. No smoke, no lag, just pure, clean power.
You can tell these guys actually test and perfect their tunes before releasing them. Everything from idle quality to turbo spool feels engineered, not guessed. Plus, knowing I’ve got lifetime updates and real techs who actually answer messages gives me peace of mind.
If you’re serious about tuning your Duramax and want a company that backs up their claims with results, Empire Diesel is the only name you need to know. My truck runs better, sounds meaner, and pulls harder than ever.
I can’t believe the difference this made. My fuel economy has improved, and towing heavy loads is now effortless. It’s like driving a whole new truck.
Great kit, fantastic customer service and easy to install if you have decent mechanic skills also videos are available to follow along all in all very happy with fit and outcome
Everything was great. The Ez link worked as I hoped it would and I am removing all the EGR and DPF equipment now.
Nothing Bad at all to say these guys are Superb. From ordering to receiving my items. Fast Shipping and on time. Added to my Favorites Tab and will be back for Future purchases. A++++++++++
