Each new application begins with dyno testing to measure and plot the factory power delivery in order to track the changes as we increase engine load values and enhance torque management to arrive at a smoother, more powerful driving experience! Additional features include removed top speed limited; increased rev limiter; improved throttle response; smoother power delivery.
