This is what FocusSport had to say....Is it BS or they right?
"As you can probably tell by the dyno charts, we're pretty excited about the results. The car has taken on a much more responsive attitude, and is without a doubt, more exciting to drive.
Although the factory motor was blessed with excellent bottom-end torque, that surge in power early in the powerband [2200-3000 rpm] was engineered for pedaling around town in a rather sedate manner.
To turn our Focus into a more thrilling proposition, it was necessary to create a powerband that not only provided more peak power, but provided it over a much wider range. Where the factory setup only exceeds 110 LB/ft of torque from 2200-3000 rpm, the FocusSport tuned setup exceeds 110 LB/ft of torque from just 3500 rpm all the way to 5500 rpm. Accentuating this impressively torquey midrange is the engine's ability to strongly pull to 6000 rpm where it delivers a staggering 28 hp increase over stock output at that rpm.
All of the products we used to achieve these results (FocusSport Cool-Flo Intake, FocusSport Cat-Back Exhaust, FocusSport 8mm Plug Wires*, and Kent Adjustable Cam Gears) are currently available, and the links are provided below. "
