I know this is an old post, but I recently came across a website called "G Force Chip Scam."
They disassembled a G Force chip circuit. It turns out that the box actually has a bunch of components but the wires in-and-out of it connect to nothing. The chip itself is a cheap logic chip wired in a nonsensical way. The system is completely bogus.
At $70 US, it can certainly lighten your billfold, but that seems to be the only way it improves the performance.
