Welcome to the site!
GForce lies. Through their teeth.
Their chip is a resistor worth a dime and a connector and housing. It tries to fool a sensor, but our engine computer is too smart and in a few miles of driving, whatever benefit they claim to deliver is gone.
Their claims are impossible.
They are a stupendous ripoff.
We won't allow them to be sold or resold to victimze others in the classifieds. There are a few other items in this category, like the "tornado swirling air intake vortex disks" and throttle body spacers.
Snake oil is a "nice" term for what I think of them and their ripoff company.
I think you get the drift.
