Ram Cummins 6.7 Full Delete Bundle | 2019-2021

Overall I am very happy with all aspects of the Diesel Dudes delete kit and would recommend it to anyone looking to do the upgrade. Initial ordering was easy and straight forward. The main parts arrived in 5-7 days shipping from Canada to TN. The last item (Shibby plug kit) arrived in 9 days which was shipped from another vendor I imagine. All of the described parts arrived in the kits.
The EZLYNK installation was a little bumpy due to me not having the specific tune that I needed for my stock 2020 Ram 2500. I went to install everything on a Saturday forgetting that it was Saturday and that I may not get an answer should I have an issue. When I went to install the tune there were a page full of options. I accessed the EZYNK chat app and got an answer back in about 30 minutes so a big great job to EZLYNK. The DT19-20 RAM PKP 68RFE SOTF 0-200HP W/TCM V5.9 was what was recommended for my stock 2020 Ram 2500 with the Banks Monster ram and Pedal Monster mods.
A word of caution for people with aftermarket plug-ins for Apple Car play or the like. You will need to unplug it or it will interfere with the EZLYNK download process. My greatest fear for this kit was some computer related **** up on my part. Fortunately I noticed the EZLYNK app was getting bumped off because of the Apple Car Play app so I unplugged it and was good to go.
Installation was straight forward and there was an initial prompt to put the vehicle on a charger to maintain a good 12v during the installation, which I would highly recommend. During the installation the screen was continuously scrolling and the chime was constantly screaming at me so it was draining the battery pretty good I imagine. The down load took about 12-15 minutes overall. When it finished down loading at the prompt I unplugged everything and it fired right up no codes, no problems. The transmission shifts are noticeably more deliberate than they were pre-tune installation. Overall not a big deal, just a little worrisome given the 68RFE reputation.
The Delete pipe was next. Unless you are 18 year old kid, you are going to want a muffler with the kit! I originally thought that I ordered the muffler with the kit, but I did not. I have one on the way now because there was just too much drone/noise to be used as a daily driver. The directions, parts and installation guide was spot on. I assembled and disassembled both ends of the pipes per the directions twice. I installed the center section and rotated the back section to line up outside of the middle section of the exhaust pipe and measured to the expnsion overlap of the center section. The overlap was 5” exactly. A grinder with a cut off wheel and deburring and it was ready to install. Very nice pipe clamps too! The muffler came in and was installed no issues. The original delete kit parts allowed me to install the muffler with what was originally shipped in the delete kit. I just had to shorten the center pipe again for the installation. You will need an additional 4” clamp to install the muffler.
The SOTF switch fit into the factory harness, but was a brutal install due to the guide rails on top of the SOTF male plug end. I hope I do not have to pull it out any time soon.
The EGR kit. Once again the directions were spot on for my 2020 and it had some extra hardware as expected. In his video, Kyle from Dark Iron Diesel addressed the rubber “O” ring issue he had for the coolant pipe insert. I had the same issue and had to use the same fix!

The metal “L” shaped bracket to support the transmission filler tube and coolant line was twisted when it was made. This prevented the coolant hose adapter from being slid into the bracket. I straightened it out the best I could and then used a small die grinder to relieve some more metal from the bracket so it would slide in when installed.
The threaded end of the hex nut block adapter for securing the bracket to the manifold/block threads were too long and would bottom out in the block before it made contact with the manifold by about 1/8”or 3mm. I did not want to take a chance of an exhaust leak or a vibration cracking the bolt so I used a spacer to allow full face contact against the manifold.
The Shibby plug kit was pricey for what it is, but I don’t see why anyone who lives in a high salt area would not buy the kit to prevent the inevitable corrosion and electrical gremlins that the salt is going to cause.
A bit of advice for anyone DIY. Place a towel directly underneath your work area in the engine bay to catch dropped parts or pieces. I probably wasted nearly 2 hours trying find a dropped nut or bolt or the coolant hose adapter. The factory manifold EGR cooler nuts x4 are stainless maybe and the hose adapter is aluminum so a magnet didn’t work to blindly find them or to pick them up.
Lastly I have about 300 miles on the install right now. The drivability seems about the same with just the more aggressive shifts being the most noticeable difference. The shifts may ...

100% as advertised. Full delete bundle with EZ Lynk, Great Documentation made Installation every straight forward. Don't know why I waited so long to apply.
Thank you!

2nd review first one was about the delivery and how awesome John was helping me get it. This one is on the product. The EGR,DPF when I open the boxes no instructions 1. I guess someone forgot to put it in the box but luckily I know vehicles and I used common sense to get the job done(if your looking at buying this kit dont worry im just unlucky) and theres youtube videos online that would help DarkIron diesel is pretty good with his videos on how too i had to use his video for tips for the DPF removal. 2. The EGR bolts was alittle too long for my aftermarket intake manifold so I took a grinder and grinder bout 1/4 inch off so it wouldn't bottom out and leave a small gap at the top of the EGR. Only 2 problems with the kit. I would have loved if the kit came with a little tiny tube of lock tight but I had some in my shop. I do love how the EGR is Blank blocker plate has a cleaner look than other manufacturers offer. And the Ez Lynk is a awesome tuner my first SOTF disclaimer for any customers this goes for any custom tunes that do ECM changes let your truck learn it for a couple hundred Ez lynk suggestion is minimum of 200miles for the ecm to learn and recommend of 500miles if you got a ECM reprogrammed at the dealership they recommend 150 miles but 200-500miles is okay best honestly. The tune feels amazing just the transmission shifts kinda rough after a bit of driving that might work its self out with the TCM relearning the tune.so if you dont like the rough shifting should pick a tune without TCM tune. With that all said I am happy with the program. Overall 8/10 on diesel dudes product and 10/10 on the tuner.

Easy to install great installation instructions. Performs great

Thank you for quick shipping and a simple easy kit! Much cleaner look and helped me stop being stressed about my truck regen like every week, definitely was starting to clog up

Night and day difference, received the wrong parts upon initial delivery, however new part turnaround was quick! Tune is smooth and fuel mpg is nearly double

I’m very happy with this kit from diésel dude, the installation was very easy without any problems

Everything went exactly as discussed.
The instructions and videos were perfect.

I asked for recommendations with the muffler and they provided clear feedback in 12 hours. Also answered questions about deleting CCV and heat grill.

I can’t believe how well it all went. From phone consultation, ordering, delivery and the install.
It was above all my expectations. Thank you so much The Diesel Dudes

Customer service was great. Fast response and fast shipping. Products showed up in perfect condition. Instructions were informative. Would recommend anyone use the diesel dudes. I will be purchasing two more of these kits.

Great product with pretty easy install. Don’t be a hero, read ALL of the instructions… a few times. There were a lot of tunes in my EZ Link, and I wish they had some better descriptions. But I found one that I think will work. Overall easy ordering process, good products, easy enough install.

Well it’s finally done. I’m very very happy. Full delete. The thing runs like a scolded dog. It was almost 10 below when I started.

Truck was having a lot of dpf issues and codes at 56k miles so I ordered the delete bundle. Order was placed around Christmas and I thought there would be delays for the holidays but I started receiving parts a couple days later. Kit came with everything and all the tech how to links and emails to help with the install. Just followed the video and had the truck up and running the next day. Night and day difference, I actually enjoy driving my truck again and there are no codes whatsoever, all gauges are reading proper temps, gears are shifting fine and best of all the truck can breath. 10/10 for everything so far, truck sounds great too!

I looked around for some time looking for the right tuner for my Truck. After lengthy consideration I choose the EZ LYNK 3.0. I just installed in 12/9/2024, but I can already tell the truck is unleashed. Not sure about fuel mileage, but the truck is completely different in a real good way. I’ll post more after some highway driving time. Thanks guys for all your help. Service was fantastic and recieved kit really quick. I will definitely do business with diesel dudes again!💪

Diesel dudes are awesome very knowledgeable and answers all my questions the parts came in fast and without any damage and fit perfectly on my truck the install was good and the truck breaths and runs great mpg gain was fantastic I would recommend these guys to anyone looking to upgrade their truck.

The kit went together with ease and programming was quick. Thanks for the fast shipping and kind help along the way. If I need a to get more stuff I will contact them again.

Very pleased. Great people to work with. Thanks to all at Diesel Dudes. 👍

I highly recommend this company and especially the 2021 Ram Delete Kit. Great experience and costumer service.
