Product Information

Product Description

2017-2023 CHEVY / GMC L5P DURAMAX (WILL NOT WORK ON L5D)

Includes 4 week Tuning support pack! 

LIFETIME SUPPORT PACKAGE (available upgrade) 
This recommended upgrade offers unlimited flashes and basic tune revisions on ALL TUNES. You’ll receive automatic tune updates so that you can take advantage of the progress that we make and enjoy the timelessness of the EZ LYNK AutoAgent 3.

SOTF SWITCH (NOT AVAILABLE YET!)
This upgrade is needed to correctly run SOTF (switch on the fly) tunes. Without the switch installed, your tune will default to the lowest power level. Installing the switch will allow you to adjust power levels and maximize your vehicle’s performance instantly.

TCM TUNING
This HIGHLY recommended upgrade will increase the line pressure in your transmission so it can keep up with all the added power your engine will be producing from the tunes. We highly recommend TCM tuning to anyone that plans on running anything more than a tow tune. Please specify if you have any transmission modifications when ordering TCM Tuning.

    Very happy with my purchase great products thank you and I loved how fast it arrived thanks again

    Peter

    Rodriguez

    I would just like to say thank you for such a great system your team sold me. I had everything I needed and made this kit installation go very smoothly. I was very nervous going into this, my boys kept telling me it will be fine. The Agent 3 device was such an easy install it was crazy. Everything connected very easily and meshed well with my Banks equipment I added with it. When I have heard folks say it will wake up your truck, I had no idea until I started driving it. Completely different truck. Thank you for supporting this equipment and making this high value upgrade a smooth one. I definitely am spreading your name out there.

    So I had a special case. I needed a tune for a 2008 C5500 Duramax. This is obviously a commercial truck. They were able to send me the handheld. My mechanic downloaded the parameters from the truck. He sent them off. I had a custom tune back in 2 days. The truck now runs great. Thanks to Dyno Diesels for a custom tune. When our government is doing everything they can to ruin diesels. Dyno has your back.

    Well let's just start this out by saying I have a 16 ram 6.7 and I ordered the ezlynk with the LION package shipping was very fast and everything was complete I deleted my rig it took a complete weekend because we had a little hiccup with the ezlynk not hooked to a technician but as soon as GDP opened the problem was completely fixed the five position switch was perfect and everything functions great the tip for the 5in exhaust is completely over the top but as a dump would look great I'm very pleased with the tunes just took my camper on a 80 mile journey and have ZERO complaints now the truck is a beast I highly suggest you go with DIESEL LION for the simple fact that it was very easy to install and use ...... on a side not I do also recommend headstuds!!!! Definitely worth it THANK YOU DIESELLION.COM for everything I will be sending business your way with all my friends

    10/10. I had a little mishap with the EGR kit getting shipped but after a late-night email, that was responded to extremely quickly. Customer service top notch. Install quickly and easily. It is a great product and a great company.

    Ordering process was great and everything arrived quickly and intact. The GDP tunes seem decent although there is some smoke on level 1 where I wouldn't think there would be any. Overall very satisfied with the product.

    The kit was just what I needed. The only thing is there one of the hose connections that is plastic and should be metal. I swaped it out with a metal one and all is good. Thanks for shipping the kit quickly.

    Installation for exhaust was pretty straightforward. Internet connection is slow where I live, so download of the tune was pretty time consuming. Also had to take off my dashboard to access unlock location for ECU. On the upside, easily added 3mpg - sometimes a little better when taking it easy. Amazing to get almost 30mpg (sometimes low 30's) out of a 1/2 ton pickup truck.

    Exhaust came in on Tuesday. Well packaged and perfect box. Got the truck completely done today. Slow day at the shop so I got it all done. I want expecting that much power honestly. What a difference. Already 3.5mpg better. Truck is a monster now. Shocked really. Sounds sick too!!!! Thank you guys for the product, communication. Perfect. It's like a new truck.

    Harrison

    I like it, the install wasn't too bad. Wish it would've came with instructions, that would make it a lot better.

    Marcus

    Moore

    Kit was great so far 5" was very tight at the down pipe had to bend it on frame side. And had to weld up the clamps that hold exhaust together they were a little chincy other than that no complaints at all.

    John, I'm a big thumbs up on your team overall. Very pleased with the level of support prior to, during, and after the changes I made. The number one differentiator between your team and others is the ability to pretty quickly get a live person on the phone and if needed for them to remote into the laptop connected to the vehicle. There were a few issues, but quickly addressed and or your guys confirmed for me what was happening and that all was well and as expected. Good work by all! A+ so far! Thanks Chris

    EGR kid was a breeze, for me at least. Everything I needed was in the kit. Only thing I want to say to help for future kits, is that the gasket for the intake neck/tube, it was bent and on the verge of tearing. I was able to reuse the original one on my truck since it is a very low mileage truck. Otherwise, thank you and hope I can find something on your website I can use!

    Anthony

    Worked great, will use again if needed!!

    My feedback on Jeep Cherokee | Ram 1500 3.0L Eco Diesel EGR DPF DEF Delete Kit: Very happy with the setup. Some issues I had was the exhaust hitting the transmission mount. The bend that it comes with was not enough so it rubs. It needed better instruction for the "Jeep" model EGR Delete. All I could find was for the Ram. The Ram is slightly different than mine is, routing back to firewall heater core hose, mine does not have that and I had to simply cap a line off. The upper had the holes drilled in wrong spots for my metal tube coolant input. I just cut your bracket and deadhead the input side from just the loose piece. Otherwise I am happy I do not have the crap egr,def,and the dpf is gone!!!

    Eric W Fulton

    Worked great! The kit had everything I needed to fix the issue.

    5 stars Fast shipping, quick response to my email, excellent products. Tune loaded quickly with no issues and shifting is smooth with the tow tune but I'm still experimenting. I needed a exhaust that wasn't to noisy and yours a worked perfectly and no leaks from the clamps. I did remove the 4 inches from section of straight pipe to fit my long bed crew cab but that seems to be the norm so the same pipe will fit the long bed mega cab. You were a word of mouth recommendation and I'm glad I remembered the name of your company. Thank you for helping me bring my truck back to life.

    Very satisfied with the results of the Tow Haul tune, good service and fast shipping. I do however like talking to someone on the phone more than communication thru email. (I'm just a little old school I guess)

    Lower RPM when cruising on the highway at 70! 1600 RPM and also a nice gain in mileage.

    Very happy with my order. Could have used some instructions on the install. Thanks Youtube. Also don't really understand the trans tune. Didn't get any verification it was installed on the tuner or even how it is installed. Don't even know if I really have it.

    Packages arrived and in good shape. When I had any questions someone would follow up with an answer. My RaceMe Ultra was easy to install and had no problem with the EGR delete kit. I did have a problem with my pipes due to the bend in the pipe that replaces the muffler. Only 2 ways I could put it. The bend up or down would not let me hook up my hanger mounts for support.

    Great kit. Truck runs great. I went from 16.2 highway mpg to 19.9 highway mpg. The kit did not substantially increase exhaust noise, the truck is still quiet for a diesel. I am very pleased. I can now go down to grand isle fishing and not have to worry about my truck saying in 50miles your truck will only go 50 mpg. What a relief!
