Jason from Illinois was running a competitor’s ‘ten second package and tune’ before switching over to Tapout. His car produced a very respectable 598 whp at that time. We helped Jason remotely to resolve some drivability issues, and made the car a lot more fun to drive. Then today we strapped it to our in-house dynamometer and unleashed even more power. His final numbers were 613 whp and 640 wtq!
