Omar, loved your customer service and thank you for staying late to take care of the shipping dilemma. I appreciate you going above and beyond. Not to mention my new turbo rocks and my truck is running like a beast! Thanks again for all you do. Great customer service and working directly with an owner that cares about his clients is sadly a rarity these days. Terry D

Chris at Dieselogic did an excellent job of finding the information I needed to get right injectors for my truck when Dodge and Cummins couldn't.

Excellent product and great people to work with from the order desk to the tech. Thankful that I found a company that backs up what they sell. Thank You!
