Five stars, very responsive!
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
Great job as always! Fit perfect and fast shipping! Thanks!
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!
My order was shipped right out and I received it quickly. I am very pleased with your service and product. 5 stars!
Everything went well. Thank you very 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
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.
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.
These guy(s) are great! Knowledgeable, friendly, helpful. Highly recommended.
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!
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
Easy to install, great service, the mini max is working great. Thank you!
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)
I love all my products and my truck runs great
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.
So far it has done great!!!! Not hard to install
19% Better MPG. Sounds like a REAL diesel. Great communication.
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-
Works great thank you so much 5 stars
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
The product worked perfectly, solved all my problems. Thank you.
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.
Awesome parts and shipping
I wood give them 5 Stars on my order. I'am very please with my exhaust system. Thanks
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.
Exactly what I needed and wanted.
Awesome products at an amazing price. Everything was so simple to install and program. I would highly recommend your product to everyone
Everything fit and is working very well. Order was delivered faster than expected. Would recommend this kit to others.
Lower RPM when cruising on the highway at 70! 1600 RPM and also a nice gain in mileage.
Everything went well. Took me 4 hours to complete, solo. Only gripe I could have (which I don't) would be the lack of instructions for the bracket that bolts to the exhaust. Took me a while to figure that out as the instructions showed a different set up. Preciate the kit. Have recommended to other folks.
Yall did great! Fast service and overall great experience!
It was easy and it makes the truck run better
Hats off to diesel lion. I purchased my 6.7 ford tuner approximately three weeks ago I received my tuner within three days of ordering, which was fantastic. Wasn’t expecting it for a week to a week and a half. when I received it, I opened up the box to see what came with it and noticed the gauge wasn’t in the box was planning to put it on the upcoming weekend was very disappointed at the time. I thought I was gonna have a heck of a time trying to get a hold of them and resolve the issue I first called them no answer then email them got an answer with an hour after hours. I sent them photos of what I received in the box and the person that have been talking to said he would send me one out, I thought well it’ll be another week or two before I received it. I got it within two days again very very happy with their response and concern they sent me a whole new unit very appreciative to diesel lion the way they handled it very very happy with them. Long story short if you need to order tuners or anything and need good service order from diesel lion they will take care of you. Thank you again diesel lion. If there’s anything else I need I will definitely order through them. Thanks again Cardel Howell.
I am wicked happy with the kit I received. I was proud that I was able to do the installation.
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'm so happy with the parts and I'll definitely keep buying them for you guys. Thank you.
Everything worked out perfect, instruction very accurate
I am very pleased with everything purchased from here. All went smooth with no installation issues. Thank you for making my truck awesome!
Very happy with my purchase great products thank you and I loved how fast it arrived thanks again
A highly recommended group of people. WIlling to help on what would normally be out of business hours. I'll be coming back for their help in the future.
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.
Yes very happy with all your service. Thanks
Ok. We did the download from your email. TRUCK RUNS GREAT!!! THANK YOU!!!
Everything I needed was in the kit I was very happy with Everything except the shift on the fly selector. I spent 2 hours installing it in a very inconspicuous location. After I installed it we could not get the proper voltage reading for it to work correctly with my truck. So now I have it still mounted in my truck but I had to unhook it so it was a $150 item that I won't be able to use. But everything else worked very well and I am pleased with the outcome of the installation. Thank you for your products. Will be purchasing more form your company in the future
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!
Very helpt and really like the quick reply's to any question I had Thanks
Received everything very quickly!
I like it, the install wasn't too bad. Wish it would've came with instructions, that would make it a lot better.
THIS WORKED AS IT SHOULD-NO PROBLEM INSTALLING -THANKS
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.
Hey guys just a shout to you all! Thanks for supplying us with another great kit. Everything went together perfectly and the tuning is awesome! Thank you for another great experience!
good tunner worked the way they said.
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 product will be ordering more very soon!
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
Works awesome.
Thanks I appreciate you.
Awesome! Install wasn't too bad on 2017 Ecodiesel Ram 1500. Truck is much more responsive and should last longer now that I am no longer spewing carbon into my intake manifold.
Yes very happy with both my orders
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
I am extremely happy with my product I ordered. Easy installation and everything was well packaged.
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!
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.
I'm very happy with the service and the fast response when I had any questions thank you very much
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.
Everything worked out perfectly. Super happy.
You did very well thank you so much.
It is amazing! Truck runs like a dream!
Everything works great and the whole process was much more simple than I expected. I will definitely be recommending you to others. Thank you!
Thanks for the promoptly sending my order. Everything fit great. I'm totally satisfied!! Thanks 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
Great feedback with issues with software. Very responsive and helpful. Great customer service for products.
Thank you this worked it was file E! Tunes are great
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.
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.
You guys are lifesavers , everything thing went together perfectly, runs and shifts better than ever and it was delivered the same day I ordered it. You gained a loyal customer and I appreciate the entire process, thanks again
Did exactly what I wanted.... And would definitely recommend
The kit was fantastic. My stage 2 tow tune is a good tune.
Hey, it all went well the freezer did the trick (on mm3), it all went back to stock and then everything loaded on. It's awesome, I am very happy truck runs like a dream transmission is buttery soft. Very impressed. Thanks for all your help and good service ií will definitely recommend you to my friends. Thank you again
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!
You guys are the best, thank you.
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.
I'm very impressed by the sound and power it makes when I get on the throttle(WOW😁)
Awesome company, great products/tunes!! Very fast customer service!
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).
Hi there and sorry it took me a long time to get back to y'all. I f**king love the way my truck runs and sounds now . Thank
Great company to deal with will definitely use them again
