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
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.

Great product and super nice customer service
Everything went well. Thank you very much
Works awesome.
Thanks I appreciate you.
Truck runs great now. 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)
Awesome company, great products/tunes!! Very fast customer service!
You guys are the best, thank you.
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 so happy with the parts and I'll definitely keep buying them for you guys. Thank you.
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.
Great everything worked perfectly!
The best product and excellent customer service!
Wow what a difference should have installed a raceme ultra years ago. Truck runs great
Absolutely amazing customer service and shipping. Have told several people to do business with you. Couldn't be happier. 5 stars all the way
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
Awesome parts and shipping
Everything worked out perfect, instruction very accurate
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.
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.
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.
19% Better MPG. Sounds like a REAL diesel. Great communication.
Everything went good on the install
EFI Live easy to work with! fast shipping! Thank you
Everything fit and is working very well. Order was delivered faster than expected. Would recommend this kit to others.
Install went awesome, instructions were good and everything went smoother than expected. Thank you.
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
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 am very pleased with everything purchased from here. All went smooth with no installation issues. Thank you for making my truck awesome!
I am wicked happy with the kit I received. I was proud that I was able to do the installation.
Great feedback with issues with software. Very responsive and helpful. Great customer service for products.
good tunner worked the way they said.
Hello, your kit worked awesome. No issues at all. Truck runs great. Thank you
Lower RPM when cruising on the highway at 70! 1600 RPM and also a nice gain in mileage.
Great company to deal with will definitely use them again
Will give these guys a 5 star plus! Thanks for the discount and quick shipping. Highly recommended.
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
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.
%100 great service awesome timing on parts!
The product worked perfectly, solved all my problems. Thank you.
You did very well thank you so much.
I am extremely happy with my product I ordered. Easy installation and everything was well packaged.
The truck is running pretty good now thanks to your tunes and email help. I ran the 60hp tune for a few days then loaded the 100hp. Ran a tranny learn session out on the interstate immediately after the flash. Truck runs better on the 100hp than the 60hp tune in my opinion. No rolling coal, just a little "coal dust" when accelerating. The mileage is fantastic compared to what it was getting before the turbo replacement and tuning. It was 13-14 mpg before the swap. Now running the 100hp tune, I'm getting 21-22mpg. Unbelievable! On a fresh refuel, I reset the mpg display on the truck. The first 125 miles saw 22.5 mpg! After five days of mixed driving, it was still holding 21.8 mpg. Now, the big question is: How accurate or valid is the PCM calculation and display? Who care? Before it was reading 13-14 m mpg. Now it's showing 21.8 mpg. That makes me happy and that a good thing. I will run a manual calculation when I refuel again in a few days to cross check. Thanks again for your help and patience.
I'm very impressed by the sound and power it makes when I get on the throttle(WOW😁)
Worked great! The kit had everything I needed to fix the issue.
Thanks for the promoptly sending my order. Everything fit great. I'm totally satisfied!! Thanks again!
Exactly what I needed and wanted.
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.
Very nice, everything was on time and how it supposed to be thanks guys
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 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.
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 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
Everything was handeld very well and all the stuffed worked no problem
Great product, had everything I needed. Installation went great, got it all done myself in my garage in about 6 hours. Truck runs awesome with engine and trans tunes.
Five stars, very responsive!
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
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
Works as it should. Quick shipping
Great service. Fast shipping. Great product. Will do business with you guys again!! A++
Incredibly happy runs way better mileage increased and muffler with 4" exhaust is perfect. Thanks again
Did exactly what I wanted.... And would definitely recommend
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.
It was easy and it makes the truck run better
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.
Awesome products at an amazing price. Everything was so simple to install and program. I would highly recommend your product to everyone
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).
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!
The best customer service in the business!!!!
Worked great, will use again if needed!!
Thank you this worked it was file E! Tunes are great
Product was great. Easy installation. Great improvement over stock.
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.
Truck is back to running like it should thanks
Installed this kit a week ago so far it has been doing good.
Thanks
Yes very happy with all your service. Thanks
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.
You have a very organized company it came right on time thank you
Excellent!!!!! Everything worked out perfect
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.
It was great so far so good 👍
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 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!
A PLUS. Everything was perfect. Tunes work as they should. Drivability is better than factory programming. Very happy and will buy from again.
