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.
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
I am really like y'all customers Servies Very helpful.
Truck is back to running like it should thanks
Truck runs great thank yall
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.
Yes very happy with all your service. 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.
Everything was great my order was exactly what I wanted no hassle no problem. Would definitely order again from Y'all again.
Product was great. Easy installation. Great improvement over stock.
The kit was great and super easy to install. I didn't see the transmission tune.
Thank you this worked it was file E! Tunes are great
Instructions would be awesome. But overall very happy with products performance
The best customer service in the business!!!!
Fast shipping and good fitment
Great company to deal with will definitely use them again
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
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
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 product and super nice customer service
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-
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.
Worked great! The kit had everything I needed to fix the issue.
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!
It is amazing! Truck runs like a dream!
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
Did exactly what I wanted.... And would definitely recommend
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 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
Ok. We did the download from your email. TRUCK RUNS GREAT!!! THANK YOU!!!
Great product will be ordering more very soon!
Everything went good on the install
Will give these guys a 5 star plus! Thanks for the discount and quick shipping. Highly recommended.
Everything fit and is working very well. Order was delivered faster than expected. Would recommend this kit to others.
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
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.
Initially hesitant about deleting, I found that it turned out to be the best thing I could have done. As a result, I no longer experience exhaust service lights, and there is no lagging when I step on the accelerator. Additionally, I have noticed an increase in fuel mileage.
Great service. Fast shipping. Great product. Will do business with you guys again!! A++
good tunner worked the way they said.
I love all my products and my truck runs great
thanks again the truck runs great went from 27 to 32 mpg
Five stars, very responsive!
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.
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
Awesome products at an amazing price. Everything was so simple to install and program. I would highly recommend your product to everyone
So far it has done great!!!! Not hard to install
It was great so far so good 👍
Installed this kit a week ago so far it has been doing good.
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.
Good service prompt delivery!
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
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)
The product worked perfectly, solved all my problems. Thank you.
Everything worked out perfectly. Super happy.
Yes very happy with both my orders
Excellent service and parts... Fast shipping!
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 everything worked perfectly!
Awesome company, great products/tunes!! Very fast customer service!
Great job as always! Fit perfect and fast shipping! Thanks!
Great feedback with issues with software. Very responsive and helpful. Great customer service for products.
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.
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
Great products and lots of good assistance with the purchase!!! Thanks!!!
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.
THIS WORKED AS IT SHOULD-NO PROBLEM INSTALLING -THANKS
Awesome parts and shipping
Thanks for the promoptly sending my order. Everything fit great. I'm totally satisfied!! 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.
19% Better MPG. Sounds like a REAL diesel. Great communication.
Very happy with my purchase great products thank you and I loved how fast it arrived thanks again
These guy(s) are great! Knowledgeable, friendly, helpful. Highly recommended.
Very helpt and really like the quick reply's to any question I had Thanks
Wow what a difference should have installed a raceme ultra years ago. Truck runs great
Truck runs great now. Thank you.
Works great thank you so much 5 stars
I am extremely happy with my product I ordered. Easy installation and everything was well packaged.
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 works great and the whole process was much more simple than I expected. I will definitely be recommending you to others. Thank you!
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.
Absolutely amazing customer service and shipping. Have told several people to do business with you. Couldn't be happier. 5 stars all the way
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.
I'm very impressed by the sound and power it makes when I get on the throttle(WOW😁)
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
