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!

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.

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.

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.

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.

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

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.

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.

Javier

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.

Jeffrey

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.

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.

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.

Terry

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

Jeff

Watkins

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.

Tracy

Funderb

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)

Mike

Great everything worked perfectly!

Dave

Skibinski

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).

Tyler

Cline

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!

Dianne

Brooks

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.

Andy

Kosevich

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.

Adam

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

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.

I'm very happy with the service and the fast response when I had any questions thank you very much

Eliazar

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.
