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.

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.

Diesel ops I ordered a programmer, pillar mount, egr / throttle valve delete, intake, and 5" tbe for my 2016 Ram 2500. Diesel ops (Chris) was very knowledgeable and assisted me with putting a package together along with a very competitive price. Parts were processed and shipped quickly. I will be a future diesel ops customer.

Ordered a tuner for my farm truck and… Ordered a tuner for my farm truck and installed it and my truck ran worse than before it was installed. Sent an email for a return label and got a return email that said they don't except returns on parts that had been installed. I'm out $500+ for a tuner that does not work... Will never order from them again. Be careful about ordering from them.

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.
