I ordered 6 reman injectors mid afternoon and 18 hrs later they were in my hands and the freight was free as was the return of the cores prepaid, a very novel concept in this day and age. I installed the injectors in a engine with 7700 hrs on it, it had started to smoke especially at idle. I tested the engine before ordering and found at least one injector over fueling on a cylinder contribution test, cyl cutout test found the smoking injector. Now I have a truck that runs well, no smoke, pulls well, and you might say runs like a kitten full of cream. Thank you DPC for a great product and excellent service.
The quality of the product is excellent. It's like having a new truck again! Also, customer service was prompt and extremely helpful!
