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%

Called and emailed and got nowhere with them. Paid for a turbo back and got screwed with a cat back. Be very careful doing business with this company. Not honorable! Bob

Didn't recieve shipment... Just hope nothing goes wrong with your shipment or ordering process as I've called and emailed this company over the past couple weeks and still no head way as far as where my package is. I was supposed to recieve it about a month ago. Customer service is defintely lacking here. Very unhappy.

Great company to buy from. I purchased a kit for my powerstroke with h&s mini maxx. I couldn't install the tuner tof my truck so I tried to call hs and they are out of business. So I called dieselops.com, someone said they could help me and would send an email with instructions. I waited 2 days for the email before calling another company who sells these tuners, who helped me over the phone within 10 minutes. So long story short, they sold me something at a great price, and didn't offer any troubleshooting help. Won't be using them as a supplier anymore.

Being a micanic I have found that it … Being a micanic I have found that it can be hard getting solid advice on a part wether it be first hand experience with its quality or many hours of research. On top of getting someone who can camunicat in an engaged sence of interest with the product they are selling. So I fully appreciate being a stranger on the phone and getting good guidance. I only credit the advice after I had installed the kit and found a leavel of trust in diesel ops for them telling me every thing I should anticipate during and after installation. I will definitely be doing more buissnes with them.
