I recently purchased a used modified ATS-V and reached out to several tuning companies to try and find out more information about what was done to the car. Scott with Tapout Tuning responded quickly to my email and as it turned out his shop had done substantial work to the car for a previous owner. Scott sent me a comprehensive email with all relevant information of what was done to the car along with dyno charts. Once I had purchased the car Scott took his time to tell me about what he recommended be done since it had been several years since he had seen the car and spent quite a bit of time making sure the tune was good on the car and advising any work that should be done to make sure the car was making safe power. Throughout the whole process they were extremely responsive to email and would always quickly ship out parts that I needed. Needless to say Scott and his team went out of their way to help me and made my new car run fantastic and I would highly recommend this shop to anyone looking for any work to be done!
