I had been struggling with my Silverado’s ECM for weeks, and finally decided to order this replacement unit. The best part was the programming service included—they had it VIN programmed and ready to go right out of the box, which saved me a ton of hassle. Shipping was also super quick and didn’t cost an arm and a leg, which I really appreciated. The moment I installed it, the truck fired up without any issues, and all the previous error codes disappeared. Their team was very responsive too, answering my questions promptly when I reached out for clarification. Overall, this was a smooth and reliable experience from start to finish.
