The guys at diesel ops are helpful they are willing to help with any questions you have also I was looking and an exhaust and tuner for my truck and found a package I liked and they offered a different package that was a little cheaper they didn't push it on me but they offered and answered the questions I had about it really easy to work with.

Choosing the right package and making my purchase was a breeze! Shipping took almost 2 weeks but well worth the wait. Price was not the lowest but still competitive and worth the extra few dollars to have the support available.

Had the exact kit I was looking for. Received my order very fast. Customer service was very nice and helpful. Great prices too.

I purchased the wrong tuner and it was easier returned for the correct one. They have my business.

I spoke with a representative at DieselOps about the best option for my truck. Not only did he refer me to what i believe was the best product, he shipped it same day from a facility nearest me so i received it the next day. More than expected, kudos dieselops team.
