Scott did an amazing job tuning my CT4-V Blackwing. I appreciate his iterative process of tuning the car. Start with small gains and works his way up, making sure the car is happy with what has been done. He also did a very good job of keeping me informed of what he was changing and why. After the final dyno pull, they took me on a test drive to ensure the car was happy out on the road during hard pulls. To say the least, it was impressive. Once the tune and test drive was done, I drove the car 400 miles home and managed 26 mpg. I highly recommend their services.
