"Great customer service"

Great customer service, always got through when I called! The person who answered the phone was able to quickly and efficiently answer my questions. I just installed the kit I bought from diesel ops this weekend and I couldn't be happier!! The only reason I can't give 5 stars is because I ran into to a problem with the tuner, i had to research by my own accord to find out how to make it compatible with my truck. Otherwise 100%

"I’m waiting for another part they sent …"

DieselOps is a 1st class co. I was waiting for a part to be delivered it was taking a little longer to get here but it was not there fault it was ups lost my package and I called them and Chris gave me his Direct number so he could find out what happen and to rush me a new part i needed it was great to talk to someone you could speak English and was a local company and the parts for my F-350 are at a great price and that Chris handle my problem right away thank Chris for all your hard work at DieselOps

"Customer service was very good to deal …"

Customer service was very good to deal with

"Very pleased"

I bought the H&S delete kit with 5" exhaust and S&B intake, very good deal for everything and I am happy with it. I did have 1 question during install and the guy was very helpful and friendly. The only thing was it all came in 3 different packages on 3 different days so I had to wait to do my delete but I survived the wait. I would/will absolutely buy from Diesel Ops again!

"Better MPG and more HP BEST INVESTMENT"

Shipped well and nothing was missing for the install. Its like buying a whole new truck with the new performance. Would recommend anyone with a diesel that wants to increase MPG and HP go through Diesel Ops. Only downside is they have an allen wrench bolt for the throttle valve delete kit and had a bolt break off when tightening down (probably installer error). I replace all those with 10mm bolt that I pulled off of the existing and was much easier to install and create a good seal on the gasket.

All in all best investment I have made on my truck since buying my truck.

"Great Company"

I'm stationed overseas so it's not always easy to get parts for my truck. Dieselops worked with me and made sure I received my stuff with no problem. They are great company and I look forward to ordering more stuff for my truck with them. Thanks for everything.
