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.

David

Woodc

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.

Jeramie

Speck

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.

Scott

Stribling

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

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

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

Marty

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.

Roman

The kit was fantastic. My stage 2 tow tune is a good tune.

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.

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.

You did very well thank you so much.

Terry

Conk

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.

Mike

Thompson

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!

Brett

Nichols

You guys did awesome!!!

Whitney

Schiesser

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.

Yall did great! Fast service and overall great experience!

Travis

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

Lower RPM when cruising on the highway at 70! 1600 RPM and also a nice gain in mileage.

Brian

J

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

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.

Cordy

DD

Worked great! The kit had everything I needed to fix the issue.

Tommy

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

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.
