Fast shipping, very helpful when I called to ask for some problems I was running into

Overall, I am very happy with the finish product. Although, I highly encourage using lots of penetrating oil for older truck installations.

EGR ruined my 6.4 at 70k miles. Had to put in a factory rebuilt engine. Took off 200# of emissions crap and put on a complete delete kit from the start. No more 3 second turbo lag, doubled my mileage from 9 to 18 !!!!!!

Awesome experience
By Chelsea W.
I went with Diesel ops when I found out they were a local Michigan company and a hour away. I called to get just a quote because I was price checking between companies. After talking with Korey for awhile on what I wanted to do he said he would put a package together for me and beat any competitor prices. I was sceptical at first but he called me back at closing time with a price $200 cheaper that anywhere else. So went with it and he stayed like 30 mins late to get my order in. I had a issue with firmest of one of my parts and I called to tell them I was unhappy with it. I ended up placing another order to correct it and I'm returning the parts I tried and modified to use at full refund. I'm happy with my purchases and customer support from Diesel ops. I will be purchasing more upgrades in the future and they will be my go to guys. Thanks again
