I was really impressed with how smoothly the whole process went. The ECU arrived quickly, and it was already VIN programmed, so installation was basically plug-and-play. The shipping was very reasonable, which was a nice bonus compared to other sellers I looked at. It’s like the engine woke up after I installed this unit—runs perfectly now with no warning lights. They even answered my questions promptly when I reached out, which gave me extra confidence in my purchase.
