Customer Reviews
Overall rating: 4.6 / 5 from 167 reviews.
Over all I am extremely happy with this kit. Things that need addressing: You have to ask for the installation instructions for the EGR delete kit to be emailed to you. The EGR kit does not come with the barbed/NPT threaded nipple adapter like other kits do. It also doesn’t have a good locking mechanism to hold the orher end of the heater hose into the junction. (See photos). There for I had to use galvanized wire to secure it because it eventually started to separate even though the plate was holding it together. The stainless exhaust is awesome. I did the upgraded to 308 stainless and it is high quality! I didn’t have to trim or cut the pieces at all on my short bed mega cab. Once I figured out how to install the programming into the the tuner that was also pretty easy. Customer service is very good and quick to reply to emails and they are Americans, if you call in.

Downloading was a breeze. Truck performance is awesome. MPG went up about 8 miles to gallon. The transmission shift points could be a little better. Overall the tunes provided by them are great.
EFI Live AutoCal Tune Package for Dodge Ram Cummins (2006-2021)
Received my 2019 Ram 2500 complete delete kit in 5 days from ordering, all parts arrived undamaged. The install was not too complicated assuming you have some mechanical abilities and are comfortable tearing your truck apart. Highly recommend shorty 15mm for one of the bolts on the EGR elbow on the front of the engine, that was the biggest pain out of everything. My truck sounds amazing now!! I could not believe how much better the truck drives and sounds. Customer service was super responsive as well, I reached out several times with a few questions along the way from ordering to install and they responded quickly and with the information I needed. I would definitely order from them again.
Ram Cummins 6.7L All-in-One DPF/DEF/EGR Delete Kit (2013-2021)
Solid tunes truck feels good not much smoke at all. Trans seemed to slip in second right after the 1-2 shift but has gotten much better for sure I think it just needed sometime to recalibrate and understand what was going on
Ryan has been great to deal with very communicative amazing response time and great service, all around price was amazing will only use Tunes Depot for all my tuning and hopefully more THANKS Ryan
Bought the full delete kit and absolutely love it!
6.7L Cummins Delete Kit | Complete DPF/DEF/EGR Delete | Ram 2013–2021
Tuner depot was very helpful I thought I screwed up on the tune part and flashing the ecm but there customer service told me I didn’t mess it up and helped me through it but one thing for sure is nothing to do with tuner depot but no one every tells you on a first time doing one of these trucks the amount of hours it takes it took me almost 30 hours which if I had the right tools and confidence I could of probably cut it down to about 20 but kit works great it’s got awesome power now and I’ll be doing the down pipe very soon to I highly recommend just buying it and getting it over with because the truck is still very quiet almost like it’s a notch above stock

22 2500 SO Absolutely loving this kit! Truck sounds like a real diesel now.. Everything came within 3-4 days, installation was super easy if you follow all directions provided. Had a few questions regarding installed mods on the truck, support and the tuner were very helpful!
Ram Cummins 6.7L All-in-One DPF/DEF/EGR Delete Kit (2013-2021)
I ordered my kit about a year ago and finally got the courage to install it. I had one moment of panic while programming the ECU. The flash didn't take and after reaching out to the support team, I overlooked the bypass wire instructions for my year truck. After swapping the wires, everything went smoothly. I ordered just the delete pipe and it fit perfectly without any cutting. I'm very pleased with the product and support that Tuner Depot has provided.
Ram Cummins 6.7L All-in-One DPF/DEF/EGR Delete Kit (2013-2021)
So glad I went with TunerDepot! These guys have the best customer service and answered all my questions leading up to my purchase. Shipping was quick as I received my kit in 2-3 days. Everything to install was straight forward. I received an email with attached pdfs that included instructions on each item except for the EGR. I found a video by Dark Iron Diesel on Youtube, very helpful for the EGR if you have not done it before. Lastly, I installed a 13-18 5" SS exhaust I had laying around on my 19. Did not fit at all, but not difficult to shorten downpipe/reweld flange in order to fit stock downpipe on my 19. Also threw on a SS muffler from TunerDepot. Sounds great, but still pretty damn loud!

Ram Cummins 6.7L Efi live Autocal V3 DPF Delete Tuner (2006-2021)
Just got them installed on my truck yesterday and cannot believe the increase in performance! Can’t wait to take it on a road trip already see more power increase and fuel mileage. Unbelievable would do it again tomorrow!
Love the sound of the straight exhaust especially on the Dirtymax they just sound badass without a muffler
Easy to use. Worked awesome really help to wake to truck and get rid of pesky emission codes once and for all
Ram Cummins 6.7L Efi live Autocal V3 DPF Delete Tuner (2006-2021)
I purchased the efi live sotf tunes along with Dpf delete kit, dpf was good quality, tuner worked with me and not only sent my autocal loaded with a sotf tune but also sent me a few single tunes to use until I installed the switch, the only negative was that 130hp was the max power tune single or switch on the fly, but over all I was pretty happy and service was very good throughout.
2003 lb7 install was easy. I will say take your time taking the plug apart on older trucks as the plastic components are brittle. Was very impressed with the performance upgrade!

Love everything about this, more power, better mileage, no check engine lights. I’m very happy!
The product you actually get is different from the picture, still worked well. But would have been nice to have an accurate representation.
Did not fix on the fling correctly where the downpipe sits and was pushing upwards towards frame

Pretty straight forward install
6.6L Duramax L5P 5 Inch Downpipe-Back Exhaust System | 2017–2026
Helped quiet down the straight 4" pipe
The tune is still not functioning properly whenever I hit the gas it shows that my traction control light pops up and says it doesn’t work anymore. Having trouble with the tune and doesn’t seem to want to properly function. I’ve been tuning and deleting trucks for a while and never had this issue
Should come with clamps
works as advertised
Everything went smooth and lined up great just wish it would’ve came with instructions
