Shipping was free, which was a nice bonus. I also appreciated the team’s quick responses when I had a few questions about installation. My 2004 Ram 5.7L is running perfectly now, and I couldn’t be happier with the quality and service.

The plug-and-play setup made the installation process surprisingly easy, even for someone who isn’t a professional mechanic. After having my truck sit idle for a while, this unit got it running smoothly again without any hiccups. Opting to buy this online rather than going through the dealer ended up saving me a serious chunk of change. The communication from the seller was helpful and timely, which made me feel confident throughout the entire purchase. Overall, a great experience that I would recommend to anyone in need of an ECU for their 2004 RAM.
