Probably the increase HP that they claim is from the HP that we lose due to the fact that they use cables that are 10 times less impedance as higher resistance from factory ground cables affect the ignition system and other electrical system components, obstructing the performance of our crossfires. It stabilizes the voltage flow from the battery so that our cars can maximize the full HP.

I would have returned this product and rather have my Upsolute chip reflashed for $150 (just to be sure that my XFIRE is really chipped) if I'm not happy with it but I've noticed some significant power after I installed the hypervoltage system, therefore, I'm keeping it.
