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!!

Baros

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.

Will give these guys a 5 star plus! Thanks for the discount and quick shipping. Highly recommended.

Excellent!!!!! Everything worked out perfect

Mitchel

Johnson

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.

Geoffrey

Great company to deal with will definitely use them again

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.

Harrison

Lansdale

%100 great service awesome timing on parts!

Jesse

Ward

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

Rich

Harris

I like it, the install wasn't too bad. Wish it would've came with instructions, that would make it a lot better.

Marcus

Moore

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.

Kenneth

Polley

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.

Doug

Miller

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.

Daniel

Johnson

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)

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

Jay

Thompson

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!

Anthony

Bran

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).

David

Murphy

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.

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

I'm really happy with the Ecodiesel delete kit, which comes with an ECM and transmission tune.,My first impressions are really positive.,I installed this kit last weekend and the results have been outstanding in terms of power and fuel efficiency.,My 2016 3.0L Ecodiesel was in bad shape, stuck in 'limp mode' due to an electronic throttle fault and a DPF that was completely full.,The dealer wanted to charge me over $3,000 to replace the DPF filter, but I decided to do the installation myself.,While it was a tough process, it was definitely worth the effort.,After completing the hardware installation, I cleared the engine codes and downloaded the ECM/transmission tunes.,I went for the 40hp tune, and I can really feel the difference - there's better throttle response and a 2mpg improvement on rural roads so far.,We'll have to wait and see about the long-term durability, but I'll definitely update if I run into any issues.,Overall, I'm really pleased with the product, the instructions, and the customer support.

My feedback on Jeep Cherokee | Ram 1500 3.0L Eco Diesel EGR DPF DEF Delete Kit: Very happy with the setup. Some issues I had was the exhaust hitting the transmission mount. The bend that it comes with was not enough so it rubs. It needed better instruction for the "Jeep" model EGR Delete. All I could find was for the Ram. The Ram is slightly different than mine is, routing back to firewall heater core hose, mine does not have that and I had to simply cap a line off. The upper had the holes drilled in wrong spots for my metal tube coolant input. I just cut your bracket and deadhead the input side from just the loose piece. Otherwise I am happy I do not have the crap egr,def,and the dpf is gone!!!

Eric W Fulton

The best product and excellent customer service!

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.

Very happy with my purchase great products thank you and I loved how fast it arrived thanks again

Peter

Rodriguez

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!

Steven

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

Tim

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.

Gary

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.

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.
