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.
The best customer service in the business!!!!
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)
Instructions would be awesome. But overall very happy with products performance
Everything worked perfect, on time, and you even answered an email overnight!!! You got my 5 Stars guys!!! 👍 Thanks for a great product!
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.
Great products and lots of good assistance with the purchase!!! Thanks!!!
Everything went well. Thank you very much
Great feedback with issues with software. Very responsive and helpful. Great customer service for products.
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.
Great everything worked perfectly!
The best product and excellent customer service!
My order was shipped right out and I received it quickly. I am very pleased with your service and product. 5 stars!
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.
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.
I am really like y'all customers Servies Very helpful.
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
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!
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
Good service prompt delivery!
Worked great! The kit had everything I needed to fix the issue.
Did exactly what I wanted.... And would definitely recommend
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
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.
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-
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
Exactly what I needed and wanted.
Everything worked out perfectly. Super happy.
I like it, the install wasn't too bad. Wish it would've came with instructions, that would make it a lot better.
I love all my products and my truck runs great
A PLUS. Everything was perfect. Tunes work as they should. Drivability is better than factory programming. Very happy and will buy from again.
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
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.
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.
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
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.
Hello, your kit worked awesome. No issues at all. Truck runs great. 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!
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.
Very happy with the kit, everything fits and performs well.
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.
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
I am wicked happy with the kit I received. I was proud that I was able to do the installation.
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!
Will give these guys a 5 star plus! Thanks for the discount and quick shipping. Highly recommended.
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
Thank you this worked it was file E! Tunes are great
Awesome products at an amazing price. Everything was so simple to install and program. I would highly recommend your product to everyone
I am very pleased with everything purchased from here. All went smooth with no installation issues. Thank you for making my truck awesome!
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 service. Fast shipping. Great product. Will do business with you guys again!! A++
Truck is back to running like it should thanks
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.
THIS WORKED AS IT SHOULD-NO PROBLEM INSTALLING -THANKS
Great product and super nice customer service
Everything came in and seems to work just fine. Thanks
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
Small issue with shipping on time but 5 stars
finally got it done. amazing power difference and I think the fuel economy will be better when I get through playing with it.
Yall did great! Fast service and overall great experience!
So far it has done great!!!! Not hard to install
Works as it should. Quick shipping
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 product will be ordering more very soon!
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.
The kit was fantastic. My stage 2 tow tune is a good tune.
I'm very happy with the service and the fast response when I had any questions thank you very much
Truck runs great thank yall
Works awesome.
Thanks I appreciate 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.
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!
Everything worked out perfect, instruction very accurate
Ok. We did the download from your email. TRUCK RUNS GREAT!!! THANK YOU!!!
Great company to deal with will definitely use them again
Everything fit and is working very well. Order was delivered faster than expected. Would recommend this kit to others.
Wow what a difference should have installed a raceme ultra years ago. Truck runs great
I'm so happy with the parts and I'll definitely keep buying them for you guys. Thank you.
Excellent!!!!! Everything worked out perfect
Everything was great my order was exactly what I wanted no hassle no problem. Would definitely order again from Y'all again.
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.
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!
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
