I had a wonderful experience with ECS Performance. I brought my 2004 WRX to them for a catalytic converter install and tune. They did a whole pre-dyno inspection, showed me the compression of my engine and checked all my fluids. This left me feeling confident in the health of my car. The tune they put on my car is absolutely amazing, my car drives like a dream now. I was handed a dyno graph when I picked up the car and I was very happy with the numbers the car put down. I will definitely come back here in the future. If you’re questioning if this is the place for you, the answer is YES!
