Great product and super nice customer service

David

Hancock

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

B

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

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.

Jesse

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.

Tristan

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.

Product was great. Easy installation. Great improvement over stock.

Ron

I am very pleased with my purchase!! The only thing I wish I would have got was the pyro that goes with it. I'm saving now so I can purchase that in the near future. Thank you so much!

Mark

Lujan

I am wicked happy with the kit I received. I was proud that I was able to do the installation.

Clifford

Camp

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

Rose

EFI Live easy to work with! fast shipping! Thank you

CHRIS

SWAIN

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

Jude

Gray

Install went awesome, instructions were good and everything went smoother than expected. Thank you.

Works great nice setup

Cristian

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.

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

Great!

Don

My order was shipped right out and I received it quickly. I am very pleased with your service and product. 5 stars!

Chris

Paul

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.

Chad

Loker

Well let's just start this out by saying I have a 16 ram 6.7 and I ordered the ezlynk with the LION package shipping was very fast and everything was complete I deleted my rig it took a complete weekend because we had a little hiccup with the ezlynk not hooked to a technician but as soon as GDP opened the problem was completely fixed the five position switch was perfect and everything functions great the tip for the 5in exhaust is completely over the top but as a dump would look great I'm very pleased with the tunes just took my camper on a 80 mile journey and have ZERO complaints now the truck is a beast I highly suggest you go with DIESEL LION for the simple fact that it was very easy to install and use ...... on a side not I do also recommend headstuds!!!! Definitely worth it THANK YOU DIESELLION.COM for everything I will be sending business your way with all my friends

Casey

This kit was the best thing for my truck it like a brand new truck run so good an is bad ass fast now thanks again for great kit an service

Jeff

Watkins

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

Unkel

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.

Chris

Click

Everything worked out perfect, instruction very accurate

Cruz

Tovar

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.

Bill

King

Ok. We did the download from your email. 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.

C

Lance

Benner

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

Bobby

Holt

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

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!

Jeff

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

You did very well thank you so much.

Terry

Conk

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

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

James

Crimm

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.
