Excellent customer service and the process was pretty simple overall (lots of wrenching but so worth it!). We are ecstatic with the improved performance of the truck. Tuner is excellent and easy to understand!
Very helpt and really like the quick reply's to any question I had Thanks
The kit was fantastic. My stage 2 tow tune is a good tune.
The products that I bought from your company are outstanding and your customer service is second to none thank you for all of your help. I will recommend your company to everyone. THANK YOU VERY MUCH YOU GUYS ARE AWESOME
I'm very happy with the service and the fast response when I had any questions thank you very much
The kit works great. The DPF and DEF deletion pipes fit perfectly. The EGR Kit had everything I needed and the RaceME Ultra was easy to install. The way the truck runs now is awesome, The horsepower and fuel mileage was exactly what I was looking for. The fuel mileage on my 2017 Dodge with the 6.7 cummins with from 15-16 MPG to 24-26 MPG on the highway and from 11-12 to 18-19 in town. I'm extremely happy with my purchase. Thank you.
Great product and super nice customer service
Exactly what I needed and wanted.
Did exactly what it is meant to do... go me back on the road w increased efficiency! Beyond happy with the tuner and it's ability to monitor drivetrain functions while in use! Worth every penny!!
I like it, the install wasn't too bad. Wish it would've came with instructions, that would make it a lot better.
Lower RPM when cruising on the highway at 70! 1600 RPM and also a nice gain in mileage.
Everything went well. Thank you very much
Great company to deal with will definitely use them again
Worked great, will use again if needed!!
I am stoked! Thank you ALL for being a part of the solution. It burns me up to know the amount of great engines out there being ruined by the ridiculous laws and science being forced on great Diesel engines. No doubt about it, there are less than a handful of un-needed factories blowing more pollution into the world than ALL of the diesel engines combined. Thank you again for all you do! God speed.
I pull a 48ft car hauler with my 2014 Ford 1ton, 5.9mpg and the truck would overheat. Installed the delete kit, no more overheating 12.8mpg. AWESOME THANKS
Very happy with my purchase great products thank you and I loved how fast it arrived thanks again
I really appreciate all the help. I super excited to get the products installed on my truck. You guys are awesome with the quick turn around on the products and customer service.
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.
Everything in the kit ordered worked great! I am a happy customer and will likely purchase again!! Thanks for the great products. Thank you for your time.
Truck runs great thank yall
I'm really happy with the Ecodiesel delete kit, which comes with an ECM and transmission tune.,My first impressions are really positive.,I installed this kit last weekend and the results have been outstanding in terms of power and fuel efficiency.,My 2016 3.0L Ecodiesel was in bad shape, stuck in 'limp mode' due to an electronic throttle fault and a DPF that was completely full.,The dealer wanted to charge me over $3,000 to replace the DPF filter, but I decided to do the installation myself.,While it was a tough process, it was definitely worth the effort.,After completing the hardware installation, I cleared the engine codes and downloaded the ECM/transmission tunes.,I went for the 40hp tune, and I can really feel the difference - there's better throttle response and a 2mpg improvement on rural roads so far.,We'll have to wait and see about the long-term durability, but I'll definitely update if I run into any issues.,Overall, I'm really pleased with the product, the instructions, and the customer support.
Hello, your kit worked awesome. No issues at all. Truck runs great. Thank you
Absolutely amazing customer service and shipping. Have told several people to do business with you. Couldn't be happier. 5 stars all the way
Just finished my tuner and I love it. I I appreciate the quick shipping and great customer service u provided. Everything fit perfectly and was easy to do. I give ya 5 stars no doubt!
The service that was provided was phenomenal. Couldn't have asked for better service. Placed my order and arrived on a timely manner taken into account I live in Louisiana. Truck sounds great. Thanks again.
Had my tunes and auto agent for about a month now. Super happy with results and wow was the my tuner delivered FAST, practically next day thru FedEx.
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!
Truck runs great now. Thank you.
Very happy with the kit, everything fits and performs well.
It is amazing! Truck runs like a dream!
This kit was the best thing for my truck it like a brand new truck run so good an is bad ass fast now thanks again for great kit an service

These guy(s) are great! Knowledgeable, friendly, helpful. Highly recommended.
You nailed it, great products and a great price!
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.
You guys are the best, thank you.
Yes, I am definately happy with the products and services I purchased from you! The shipping was fast and secure, arriving within 5 days of ordering. Thank you for a great shopping experience, I have several friends looking for similar products and services, and have directed them towards your company. Thanks again for everything-
Incredibly happy runs way better mileage increased and muffler with 4" exhaust is perfect. Thanks again
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.
Great kit, very satisfied with the quality and performance and your customer support is fantastic, thanks for making the 6.7 run and sound great
Wow what a difference should have installed a raceme ultra years ago. Truck runs great
Very nice, everything was on time and how it supposed to be thanks guys
%100 great service awesome timing on parts!
I wood give them 5 Stars on my order. I'am very please with my exhaust system. Thanks
Great feedback with issues with software. Very responsive and helpful. Great customer service for products.
Thanks guys, everything worked out great. My order came in on time and any questions I had, you guys we're able to answer me via email ASAP. I will definitely recommend you. Thanks again
The product worked perfectly, solved all my problems. Thank you.
Worked great! The kit had everything I needed to fix the issue.
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.
Product was great. Easy installation. Great improvement over stock.
Works great thank you so much 5 stars
Ok. We did the download from your email. TRUCK RUNS GREAT!!! THANK YOU!!!
Great service. Fast shipping. Great product. Will do business with you guys again!! A++
Very pleased with everything I got everything went pretty smoothly and is working great! Thank you guys! Would definitely shop again or suggest to others. Only complaint is on the 5-in downpipe it is a rather tight fit and kind of touches the frame there maybe a slight Factory dent or something
Everything worked perfect, on time, and you even answered an email overnight!!! You got my 5 Stars guys!!! 👍 Thanks for a great product!
Good service prompt delivery!
I received my order quickly and it was very easily installed. I was given the wrong tunes for my vehicle but it was resolved in less than 24 hours!
I'm waiting on the rest of the stuff but the employee or employees I've been dealing with have been super kind and helpful. Thanks
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.
I am really like y'all customers Servies Very helpful.
Easy to install, great service, the mini max is working great. Thank you!
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.
Install went awesome, instructions were good and everything went smoother than expected. Thank you.
Great so far seems to be exactly what yall described thank you
Five stars, very responsive!
A PLUS. Everything was perfect. Tunes work as they should. Drivability is better than factory programming. Very happy and will buy from again.
Exactly as described. I love it my miles per gallon on the highway or approximately 25 miles per gallon now at 78 miles an hour on cruise on level ground. Very happy. Not to mention all the extra horses
Yes I'm very happy with the kit I got it in and it's working great.
Everything worked out perfect, instruction very accurate
Product was not really compatible with the C/C as turbo is smaller so GDP will only give me 1 tune. I understand why but, I bought the 5 position switch was so I could adjust power as at times I do not tow and others 30k lbs. Other than that like the tune and GDP tech line was very, very helpful So can't use the 5 position switch but will keep until I install a larger turbo as per GDP. Thanks for the product and it really sounds like a truck now.
Great product, had everything I needed. Installation went great, got it all done myself in my garage in about 6 hours. Truck runs awesome with engine and trans tunes.
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.
2016-2019 GMC & CHEVY Colorado & Canyon Duramax | EGR DPF DEF DELETE KIT very nice for both kits i bought you guys, my business will be a returning customer for sure. also very fast shipping awesome Nick Therrien, owner Larocque, Valleyfield, J6T 4c8, QC
Great job as always! Fit perfect and fast shipping! Thanks!
Thanks for selling these kits! My truck runs like a champ. It was super easy to update the SCT and flash the ECU. I was a little worried but there was good instructions!
Everything went good on the install
Everything worked out perfectly. Super happy.
