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
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 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.
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.
The kit was fantastic. My stage 2 tow tune is a good tune.
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.
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
Everything came in and seems to work just fine. Thanks
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.
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
Instructions would be awesome. But overall very happy with products performance
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).
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!
You guys are the best, thank you.
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!
Works great thank you so much 5 stars
I am very pleased with everything purchased from here. All went smooth with no installation issues. Thank you for making my truck awesome!
Awesome parts and shipping
Great product and super nice customer service
Yes very happy with both my orders
The best product and excellent customer service!
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.
These guy(s) are great! Knowledgeable, friendly, helpful. Highly recommended.
Worked great! The kit had everything I needed to fix the issue.
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.
You did very well thank you so much.
Everything was great my order was exactly what I wanted no hassle no problem. Would definitely order again from Y'all again.
Fast shipping and good fitment
So far it has done great!!!! Not hard to install
Excellent service and parts... Fast shipping!
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 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!
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.
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 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!
Everything worked out perfect, instruction very accurate
Very happy with everything 5 stars
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.
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.
A PLUS. Everything was perfect. Tunes work as they should. Drivability is better than factory programming. Very happy and will buy from again.
Everything I have ordered so far has installed and functioned without fail. Shipping has been prompt. Customer service has been knowledgeable. I would recommend these products.
Absolutely amazing customer service and shipping. Have told several people to do business with you. Couldn't be happier. 5 stars all the way
thanks again the truck runs great went from 27 to 32 mpg
finally got it done. amazing power difference and I think the fuel economy will be better when I get through playing with it.
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.
Small issue with shipping on time but 5 stars
Everything went well. Thank you very much
Will give these guys a 5 star plus! Thanks for the discount and quick shipping. Highly recommended.
Awesome products at an amazing price. Everything was so simple to install and program. I would highly recommend your product to everyone
Good service prompt delivery!
Very nice, everything was on time and how it supposed to be thanks guys
I wood give them 5 Stars on my order. I'am very please with my exhaust system. Thanks
I am wicked happy with the kit I received. I was proud that I was able to do the installation.
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.
I am really like y'all customers Servies Very helpful.
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
Great so far seems to be exactly what yall described thank you
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.
The kit was great and super easy to install. I didn't see the transmission tune.
The kit was just what I needed. The only thing is there one of the hose connections that is plastic and should be metal. I swaped it out with a metal one and all is good. Thanks for shipping the kit quickly.
It was easy and it makes the truck run better
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
You nailed it, great products and a great price!
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
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!
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.
Wow what a difference should have installed a raceme ultra years ago. Truck runs great
I'm very happy with the service and the fast response when I had any questions thank you very much
Yes I'm very happy with the kit I got it in and it's working great.
Awesome company, great products/tunes!! Very fast customer service!
19% Better MPG. Sounds like a REAL diesel. Great communication.
Great everything worked perfectly!
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!!
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.
Truck runs great thank yall
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
I'm very impressed by the sound and power it makes when I get on the throttle(WOW😁)
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.
It was great so far so good 👍
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
Ok. We did the download from your email. TRUCK RUNS 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 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.
good tunner worked the way they said.
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
