They lost my package after I sent it to them for a refund because they sent me a defective tuner. So now I don't have no tuner, no refunds. they really don't care about customer service.

Diesel Ops are right on time with shipment and no hidden cost. Didn't have to call them , everything shown was shipped with a couple of cool stickers for the back window.

Lightning quick shipping, great prices, will be back to shop for more parts that is for sure.

Best prices online...Great customer service and very knowledgeable staff

Diesel Ops customer service is TOP NOTCH. I would highly recommend purchasing from them to anyone.
