Performance ground system? Anyone know...

Have any of you ever heard of a perfomance ground system for your teg, I am guessing for the motor. I came across a "hyper ground" system on the net that claims to give a car like 5hp and a few mpg on gas. Any of you ever tried or heard of one of these sytems? They are asking like $115 for the kit and was wondering if it was worth it. Just wanna know what you all think bout it.

Spend your money on other parts the ground system will not give you noticeable HP increases if any HP increases at all.

I was looking into it and wanted it because of the claim of brighter headlights, more torque. don't know if they actually work and I'll wait till there is more info.

i have the silverstar bulbs, they bright, but i want it even brighter!
