Guys we have been selling these for over 10 years. They are pretty much standard equipment on the Ford Racing Teams Top to Bottom
Specific to Independent Testing, yes of course they have been dyno'd like a billion times. I have not paid attention this year but I know for the last 5 seasons the guys winning in Coyote Stock have been running Granatelli regardless of which car.
Also we have a money back guarantee so if they don't work, just send them back for a refund. Can't get any easier than that.
The reason why torque raises like that on same applications is 2 fold. 1. stock coils heat soak and don't repeat when you beat on them & 2. the Granatelli Coils output much better under hard load so when the stock coils nose over at peak torque the Granatelli coils won't.
Have you seen the new throttle bodies we offer for the Coyote? The gains are little because the stock part moves "enough" to feed the engine - We still saw a gain.
