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
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!
Exactly what I needed and wanted.
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
Will give these guys a 5 star plus! Thanks for the discount and quick shipping. Highly recommended.
Ok. We did the download from your email. TRUCK RUNS GREAT!!! THANK YOU!!!
Could have been better on shipping notifications on tracking numbers. I had to keep on the situation of my order by constantly emailing for tracking#'s but I finally got my products and I am very happy with the end result.
Great so far seems to be exactly what yall described thank you
I am very pleased with my purchase!! The only thing I wish I would have got was the pyro that goes with it. I'm saving now so I can purchase that in the near future. Thank you so much!
You guys were great. We had a couple of questions, they were answered. Kit was super nice. Tunes were well tuned. Good company to deal with. We will be ordering our deletes from here.
Yall did great! Fast service and overall great experience!
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.
The truck is running pretty good now thanks to your tunes and email help. I ran the 60hp tune for a few days then loaded the 100hp. Ran a tranny learn session out on the interstate immediately after the flash. Truck runs better on the 100hp than the 60hp tune in my opinion. No rolling coal, just a little "coal dust" when accelerating. The mileage is fantastic compared to what it was getting before the turbo replacement and tuning. It was 13-14 mpg before the swap. Now running the 100hp tune, I'm getting 21-22mpg. Unbelievable! On a fresh refuel, I reset the mpg display on the truck. The first 125 miles saw 22.5 mpg! After five days of mixed driving, it was still holding 21.8 mpg. Now, the big question is: How accurate or valid is the PCM calculation and display? Who care? Before it was reading 13-14 m mpg. Now it's showing 21.8 mpg. That makes me happy and that a good thing. I will run a manual calculation when I refuel again in a few days to cross check. Thanks again for your help and patience.
Product was great. Easy installation. Great improvement over stock.
If I could give you guys a 10-star review I would I've also reached out to a lot of my friends that also drive diesels and forwarding your guys's information to them so that they can purchase the delete kits also a couple of my friends have fleets of trucks so they will be in contact I appreciate you guys thanks for being awesome
Works great thank you so much 5 stars
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-
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.
finally got it done. amazing power difference and I think the fuel economy will be better when I get through playing with it.
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
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.
It was great so far so good 👍
I love all my products and my truck runs great
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.
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.
Great everything worked perfectly!
You did very well thank you so much.
Thank you, you guys were great to work with and my order came 2 days before I thought it was.. I will definitely use you guys again thanks again
Great company to work with. I had a problem with my order and they took care of it right away. I would recommend them to all my friends.
I'm very happy with the service and the fast response when I had any questions thank you very much
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
thanks again the truck runs great went from 27 to 32 mpg
Truck runs great now. Thank you.
Very happy with the kit, everything fits and performs well.

The best product and excellent customer service!
THIS WORKED AS IT SHOULD-NO PROBLEM INSTALLING -THANKS
It is amazing! Truck runs like a dream!
So far it has done great!!!! Not hard to install
Lower RPM when cruising on the highway at 70! 1600 RPM and also a nice gain in mileage.
Excellent service and parts... Fast shipping!
Worked great, will use again if needed!!
I wood give them 5 Stars on my order. I'am very please with my exhaust system. Thanks
Did exactly what I wanted.... And would definitely recommend
19% Better MPG. Sounds like a REAL diesel. Great communication.
Truck runs like a scalded dog! Had issue with muffler not being sent with original order and had to switch to EZ link tuner. Other than than N that, very pleased
This product is really great. It has significantly improved the fuel mileage, going from 23 mpg to 28 mpg. On top of that, the engine now responds much more quickly when taking off.
%100 great service awesome timing on parts!
Worked great! The kit had everything I needed to fix the issue.
Five stars, very responsive!
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.
Great feedback with issues with software. Very responsive and helpful. Great customer service for products.
Excellent!!!!! Everything worked out perfect
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.
You guys are the best, thank you.
I am very pleased with everything purchased from here. All went smooth with no installation issues. Thank you for making my truck awesome!
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.
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
The best customer service in the business!!!!
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.
So far exactly what I want to achieve, smooth, no surging, trans is solid. The delay between the 3rd and 4th is a bit long. I was hoping for an earlier shift.
I am really like y'all customers Servies Very helpful.
Awesome company, great products/tunes!! Very fast customer service!
Yes I'm very happy with the kit I got it in and it's working great.
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
Your service was awesome, I was amazed how fast my order was shipped and the customer representative was very helpful. Thanks again, Steve in Colorado
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!
I am wicked happy with the kit I received. I was proud that I was able to do the installation.
Yes very happy with both my orders
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!
Great job as always! Fit perfect and fast shipping! Thanks!
I just finished installing the RaceME Ultra and complete EGR, exhaust system kit. This woke my truck up like never before and it runs great. Technical support was a great help and Michael answered all my questions in a timely manner. Looking forward to many miles with no check engine lights. Thanks again for all your help.
Yes very happy with all your service. Thanks
I am more than happy with it. I have completed the DPF removal and straight pipen install. I have not removed the EGR. I can say that I have picked up more power and 3 more mpg towing. I have an 8k pound bumer pull camper. There is a little black smoke when I punch it; none if I drive "normal". My wife said it is louder, who asked her. I have been on the fence but your price and the extra $100 off, with free shipping was the factor. Thanks for the entire process from ordering to installation videos.
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.
I'm very impressed by the sound and power it makes when I get on the throttle(WOW😁)
Everything was handeld very well and all the stuffed worked no problem
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
My order was shipped right out and I received it quickly. I am very pleased with your service and product. 5 stars!
Very nice, everything was on time and how it supposed to be thanks guys
Thank you all for help and support everything is on truck is running fine and upgraded to the hot and cold intake fuel mileage is so much better went from 9.7 pulling my skid loader to 14.8
Everything was great my order was exactly what I wanted no hassle no problem. Would definitely order again from Y'all again.
Awesome parts and shipping
Good service prompt delivery!
The product was exactly as pictured and was what was expected. The shipping was late and I paid $350 for overnight shipping and it ended up being two days and I still had to go pick it up from the shipper (FedEx).
Great product and super nice customer service
