I purchased the 4090071 ECM for my 2004 RAM Cummins, and it arrived quickly with free shipping, which was a nice bonus. The unit was already VIN programmed, so installation was straightforward and hassle-free. Their team responded promptly to my questions, making the whole process smooth and reassuring. The truck runs perfectly now, and I’m very satisfied with the quality of the product and service.
