Eleven 23 Motorsports Dyno Tuning and Fabrication 31121 Via Colinas, Westlake Village, CA 91362

"Came here with a basically stock 2016 mustang running 13s in the thousand foot. My time is now in the low 10s. I will continue to come here because they do amazing work and are very honest."

"Lack of communication, lack of respect, lack of experience. Basic hardware on a fuel system wasn't torqued. Dyno tuning will end in disaster. Save $10,000 from the engine rebuild you'll need after a Dyno session here and go elsewhere."

"These guys build some awesome cars. And their tuning abilities are second to none. top notch. I won’t go anywhere else. 5 star all the way!"

"Not sure how other people were able to give them 5 stars but from what i saw they deserve 2 at the most. Destroyed our buddys car after assuring him they would have it wrapped up by the end of the week. This isn't the only car they've blown up but when we were warned by another customer the damage was already done. Shop refused to admit fault and take responsibility for their actions. The craziest part was they still demanded payment for novice work and tuning that kills motors! Steer clear and save yourself and your car."

"Recently had my Camaro tuned and dyno’d by the guys at Eleven 23, I couldn’t be happier with the car. They were very knowledgeable and professional, and kept me in the loop through the entire process. I highly recommend the shop, and will see them for any performance work I may have done in the future."
