Truck sounds good, doesn’t drone, little louder at idle than what I expected, but these engines are noisy, so unless you put a 5 foot long school bus muffler on it’s going to be loud. Install was very easy.

Any questions I had were responded quickly and thoroughly.

I went with the full 5 inch stainless with muffler kit , EGR delete kit and EZLink tuner with shift on the fly five stage ****. This kit was shipped very quickly and was not that bad to install. I did it in my driveway with basic tools and didn’t even have to use a jack. I recommend two things however. Buy a rolling creeper, and start spraying the EGR bolts with PB Blaster three days before attempting to break them free. I soaked mine four times a day for three days and they came out easily. The hardest part was the three against the firewall on the top of the up pipe. Plenty of videos on YouTube to guide you through it. Take your time, crack, a beer, and don’t rush yourself. CUSTOMER SERVICE IS AMAZING There are many other companies you can buy this kit from but the customer service from Diesel Dudes is worth its weight in gold. Had a few issues, but the technician walked me through it and stayed on the line with me until he was convinced we had it fixed. Would definitely recommend this kit to anybody wanting to unleash the beast in their diesel truck. After you buy the kit, you will get an email with a gift card code you can use to buy swag. Love the Trump 2024 gear. Now let’s go roll coal baby !!!

The supplied heater hose I received was faulty- had 2 small holes in it and only one o-ring on the upper quick connect. I had to cut out the bad part of the hose and hose clamp a section of hard line off the original line that went to the firewall and pull an o-ring out of one of the discarded hoses. Not impressed with the aftermarket hose. Otherwise the kit pieces went on easily and the tune installed without any incident. It would be good to inform folks that the SOTF tune and switch will cause the fuel line temp/pressure code- which I was told is "normal" following the delete

My truck was staying in a constant reign cycle because of a clogged CAT.
But not anymore thanks to the help and super-fast shipping of The Diesel Dudes.

So far I’m happy with service, only reason for not giving a 5 starts review is cause I haven’t have the unit long enough, you guys are awesome

Great product, easy to install, works perfectly. Shipped quickly too!

Coolant bypass tube was welded slightly tweaked. I had to cut the tip of the tub off and make it work. Not unsatisfied as it works well and arrived in just a few days. But maybe QC could step up a little.also the hardware was chickeshit and I had to go get bigger stuff.

Great kit. really good support with instructions and videos.

Satisfied as always with Diesel Dudes products. Installed when I did my delete. Clear instructions, easy to follow and quality parts. Will be ordering again for my other trucks!

Clear instructions, straightforward installation. Everything worked as advertised, will absolutely be coming back for my Powerstroke and my other Cummins!

Okay if y’all are like me you’re looking for an upgrade tune and delete for your truck. Let me tell you I did my homework and the price for this kit is worth it 💯! Step by step help and pretty easy to do if you know your baby’s in and outs.

I’m happy with the Race me Ultra. Easy install and down load. Never knew my truck could run like this.

Install went well. Installation of tuner and egr delet went well. Only complaint is paper instructions would be nice.

All I know so far is mileage increased and truck is loader
Couple 25 mile trips so far but most are short trips from farm to farm at this point

Initially bought a delete kit with H&S tune. The company I bought it from was worthless. The H&S tune was TERRIBLE! Zero change in the truck in any power mode. Called these guys asking about a tune I bought from a different company and they spent over an hour on the phone breaking down the nitty gritty details of tunes and options I had. I went with this tune and my truck has come to life. In stock it feels stock, in level 5 “race” I’m pulling faster 0-60 then my wife’s Audi. I will brag all day about diesel dudes and moreover the RaceMe Tune! And to top it off, I had a small issue installing the download, they put me in touch with RaceMeCanada where they get the tune. RaceMeCanada spent over an hour on the phone with me going through step by step each selection in setting up the tune and sent me a replacement free of charge because they found mine had a small glitch that was minimal but speaks to THEIR customer service as well!

Everything has been sitting in the garage for the past 5 weeks finally got around to installing the tunes and exhaust only still need to do soft switch & egr delete currently just unplugged but everything went on nicely no issues. Tuning was a breeze truck sounds amazing will follow up with the rest of the install when I get to it

Along with increased power the truck went from 12 mpg to 17.5 and it tows my 5th wheel like a champ

Since I received the plug kit after installation of the delete, it was kind of a PITA to figure out which plugs went where. I had leftovers and that is concerning. Had they been in my possession during the kit install, probably less fuss, so I am chalking it up to a personal issue and not a part issue. 5 stars

Awesome product fixed all of my issues that I had with another tuner. Power levels are great with the dsp 5 switch.

I had some issues with the DEF system on my truck so decided it was time to make a change. The kit I bought with the EFI Live tuner was easy to install and when I had questions they were answered very fast and with the help of the tutorial videos the wiring was simple. The 18 is an oddball so it was slightly different that the other models directions. The mileage towing my 46’ race trailer went from 11.5 at best to 13.4 on a 550 mile trip on tune 2. I wish I had done it sooner it’s a new truck. The next thing I might do is have them build a transmission tune to get the shift flair on towing gear changes tighten up some.

Love It after 4 day of bending wrenches finally got it done and the truck runs great

Installed the tune, replaced the exhaust and drove the truck several time. Everything is great at stock level! A little smoke if you really get on it hard. I can feel a difference in the truck running easier. I hope to install the EGR delete kit in about 2 weeks to finish this project! And in November, I’ll be hooking up the 5th wheel and giving it the real test! Thanks Diesel Dudes!

once everything showed up it went smooth, just had an issue with the exhaust, but nothing a little wielding couldnt take care of

The kit was great would have been better if the exhaust was sent with a new v band clamp for attaching to the down pipe and it the egr delete kit was sent with a throttle control delete instead of having to buy that separately
