Found the same H&S Mini Maxx programmer for 649 dollars had a few simple questions after my purchase was delivered to me no one answer the phone or call me back

Their excuse there's something wrong with the truck ( it's been checked nothing wrong )or don't Gives so much attention to the numbers displayed on mini max??? Seriously!!! Installed minimax everything was great boosting 29 psi after first week drops down to 26 psi they said I had an air leak toke everything apart broke a hose in the process I bought a new hose from them checked all boots hoses gaskets and turbo for leaks everything was good still same problem 26 psi they said to keep checking ............. 🤔 9/30/17 ? How did you reload the tuner And changed settings it's never been taken off the pick up. Sorry for any inconvenience

I ordered a delete kit with mini maxx, EGR delete, and 5" MBRP exhaust. We had a little confusion on both ends. I emailed them Friday. Chris called me Monday and cleared up the confusion. I will definitely do business with them again. Thanks again Chris.

Very happy with Diesel Ops service. My order was delivered on time. I had a couple questions about installation. They had a tech guy who was great help and easy to talk too. I would recommend Diesel Ops to anyone!

I am glad I checked out Dieselops they was very helpful in getting me exactly what I needed for my truck. I had a little problem called them up they talked me through the steps to help me figure out what was the issue had a bad part they had me one to my house the next day got me going again. Awesome business look forward to dealing with them soon. Thanks Dan J.

Great company to order from, usually receive parts within 2-3 days which helps turn around time.

Very fast and quick emailing
