Great people to work with. This was my 1st time trying anything like this. I had a couple questions on the programer and they walked me through it step by step. My Dodge Ram 6.7 has never ran better. Will buy products from Diesel Ops again. Very satisfied.

Very helpful on getting the right stuff. Shipping was quick also!

I ordered the EGR/DPF delete kit with S&B filter. The parts fit perfect. Shipping was less than desirable. Received the S&B filter in two days and the exhaust with H&S tuner in four days. Had to call about the EGR delete kit and was told it hadn't been shipped. Chris shipped it two day.

Very happy with purchase

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.
