ECS was great. They were happy to work around scheduling difficulties and went out of their way to ensure that my tuning experience was as painless as possible. The experience was the best car related experience I have had. I would certainly recommend ECS for any work of questions about tuning. Thanks again!

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!

You cant rush perfection. I had my BMW 335i tuned here at ECS after upgrading the turbos and FBO. Dan has been my contact and very helpful along the journey to getting my car on the Dyno. After my 2 hour drive back home, i had no issues, the drive was smooth! The Tuner here that tuned my car did an Extraordinary job and the power output is very satisfying! I just wish i lived closer! Thank you guys, The facility was very nice as well!
