Very pleased with it, customer service was great with any questions, only issues I had was that electrical connector plugs were not available along with a better option for switch that would of had a direct connector without splicing.
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 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.
Hello, your kit worked awesome. No issues at all. Truck runs great. Thank you
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 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 I'm very happy with the kit I got it in and it's working great.
Received everything very quickly!
Small issue with shipping on time but 5 stars
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.
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.
I wood give them 5 Stars on my order. I'am very please with my exhaust system. Thanks
Wow what a difference should have installed a raceme ultra years ago. Truck runs great
Everything works great and the whole process was much more simple than I expected. I will definitely be recommending you to others. 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
Very happy with everything 5 stars
Works great thank you so much 5 stars
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.
Everything fit and is working very well. Order was delivered faster than expected. Would recommend this kit to others.
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
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
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!!
You have a very organized company it came right on time thank you
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
Awesome parts and shipping
Good service prompt delivery!
Product was great. Easy installation. Great improvement over stock.
The best product and excellent customer service!
I'm very happy with the service and the fast response when I had any questions thank you very much
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
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 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!
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.
The best customer service in the business!!!!
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 am wicked happy with the kit I received. I was proud that I was able to do the installation.
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.
It was easy and it makes the truck run better
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)
Awesome products at an amazing price. Everything was so simple to install and program. I would highly recommend your product to everyone
Works awesome.
Thanks I appreciate you.
Excellent!!!!! Everything worked out perfect
The product worked perfectly, solved all my problems. Thank you.
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.
Exhaust came in on Tuesday. Well packaged and perfect box. Got the truck completely done today. Slow day at the shop so I got it all done. I want expecting that much power honestly. What a difference. Already 3.5mpg better. Truck is a monster now. Shocked really. Sounds sick too!!!! Thank you guys for the product, communication. Perfect. It's like a new truck.
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
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.
Thanks for the promoptly sending my order. Everything fit great. I'm totally satisfied!! Thanks again!
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
These guy(s) are great! Knowledgeable, friendly, helpful. Highly recommended.
Yall did great! Fast service and overall great experience!
Great products and lots of good assistance with the purchase!!! 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 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
Yes very happy with all your service. Thanks
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!
A PLUS. Everything was perfect. Tunes work as they should. Drivability is better than factory programming. Very happy and will buy from again.
Great product will be ordering more very soon!
Great feedback with issues with software. Very responsive and helpful. Great customer service for products.
EFI Live easy to work with! fast shipping! Thank you
Will give these guys a 5 star plus! Thanks for the discount and quick shipping. Highly recommended.
Worked great, will use again if needed!!
Everything was great my order was exactly what I wanted no hassle no problem. Would definitely order again from Y'all again.
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.
The kit was fantastic. My stage 2 tow tune is a good tune.
Everything came in and seems to work just fine. Thanks
I am really like y'all customers Servies Very helpful.
Very happy with the kit, everything fits and performs well.
Five stars, very responsive!
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
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
Great job as always! Fit perfect and fast shipping! Thanks!
Incredibly happy runs way better mileage increased and muffler with 4" exhaust is perfect. Thanks again
Truck runs great now. Thank you.
You did very well thank you so much.
Excellent service and parts... Fast shipping!
Thank you this worked it was file E! Tunes are great
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!
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.
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.
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.
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.
Fast shipping and good fitment
Very happy with my purchase great products thank you and I loved how fast it arrived thanks again
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.
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.
