"Great product and great price !!"

I bought TS Performance 6 position chip and its made my 7.3 run great. Its very responsive from take off and when it shifts its very smooth. Very happy with the purchase and with diesel Ops!

"No documentation in box but, excellent online."

The box arrived with all parts inside but no paperwork. Panic! Then I learned all of that was online and easly accessed. Diesel Ops was very helpful and concerned that I initially confused and were very prompt and personable in assisting me figure everything out. I would highly recommend them.

"Mini Maxx"

Great customer service; call and talk to someone. Quick shipping. Very good prices as well.

"Thanks for good quality no mess-ups here!"

Everything came in good shape was exactly what I ordered best price!

"On Line Shopping Like It Should Be"

Had sent in a copy of my military ID for my discount a couple of hours before my purchase. Did not find discount on my dash board, made purchase anyway because I need item as soon as possible. next morning call Diesel Ops to make sure it went through, and ask about Military discount. I had made a mistake in addressing my e- mail to them for discount. They accepted my ID gave me discount on my purchase, allowed me to use my discount toward upgrade to overnight delivery of my purchase. I felt like this was a good way to do business, when item came next morning and worked perfectly, I was very impressed. They will get all my future business for my truck, GREAT SERVICE!
