Great product!

Just installed my egr/cat/dog delete kit on my 2010 6.4 powerstroke. A simple instal would of only took a day,but my exhaust bolts and sensors took me a total of 4 hours to remove. The egr delete was super easy to instal, with its great step by step instructions. Would recommend this to everyone with the regen system like my powerstoke has.

These guys are a good place to get what you need. I got a programmer and EGR/DPF delete for my truck. They sent me the wrong exhaust. After I emailed them and sent them a picture, they sent a new one with the return label with no hassle. It isnt always how fast or cheap you get something, it is nice when a company makes right on mistakes quickly and professionally. I will be buying any of my other upgrades from DeiselOps.

Hello,

First off I want to say I am glad you were happy with the service the sales team could give you , and then I want to apologize about that issue you had with the parts themselves. Rare parts made a change in their pricing program and did not notify everyone in a timely manner. This caused an issue with the order being fulfilled. I would love to make this up to you if I could so please get ahold of me at your earliest convenience.

Thank you

5 star, customer first company.

My experience with dieselops was very pleasant. Customer service was very informative and helpful on my product selection and my shipping and delivery was prompt and fast. No hassle customer service and fast shipping makes me a return customer for anything I need for my diesel rig. I give them 5 stars.

Good pricing and great help

Good pricing overall. I ordered a three piece kit that did not arrive all together. One of the boxes arrived a day later, not the end of the world, just a little annoying.
Chris "Groot" is awesome with any and all assistance. So helpful through the whole process, Chris even followed up with me to make sure everything was in perfect shape when I received it. Could not have asked for better help. Strongly recommend the guys at diesel ops.

Jeff,

I am glad you got everything and were happy with the pricing. What confuses me here is you saying it did not have the tunes in it? That is never the case all of our kits do exactly what they are supposed to do and come ready to go. I want to figure out what is actually going on here because you should not be spending more money after that kit.

Please get back with me

Looking forward to taking care of this issue for you

Thank you

Quick delivery and parts fit perfect.

Everything came quick, not shipped within the couple days stated but I was contacted about the problems they were having with the shipment. All parts fit and went together very easy.

Dustin,

I am not showing any contact from you about anything missing. I am very sorry if something was missing from the order you placed and I would like the chance to make this right. We pride ourselves on getting parts to customers in not just a timely manner but in a complete status. Like stated before we never heard from you about anything missing this means that we are unable to fix any issues and thus were unaware of them. Please reach out to us at your earliest convenience so I can assist you in taking care of this.

Thank you and I look forward to hearing back from you
