Anyone heard of these guys before? Experiences? I'm looking at trying one of their voltage or ground systems.

Hyper Ground System:
This system provides direct ground path from battery negative to body, chassis, and engine components to give extreme improvement on electrical circulation. In addition "Hyper Ground System" cables have 10 times less impedance than factory ground systems which provides immaculate conduction to prevent electrical power loss.The higher resistance of factory grounds, effect the ignition system and obstructs the primary potential.

The "Hyper Ground System" uses thick gauge 99.99% pure copper, and connects directly from the cylinder head and other points under the hood to the battery, to provide an ultra low resistance connection.This will increase the primary potential of regular cars to ignition tuned vehicles.

Hyper Voltage GT:
The new Hyper Voltage GT System is designed to stabilize voltage in your vehicle for maximum battery efficiency, allowing its full potential to be released. H.V.S. GT Version provides both function and stylish appearance; units are designed to universal to fit any vehicle, with mounting brackets and one (1) additional grounding cables.

Benefits
•Multi-Range Rev. Performance
(Low-Mid-High)
•Increased horsepower
•Increased torque
•Increased throttle response
•Improved fuel efficiency
•Brighter headlight
•Reduced audio noise
•Improved battery efficiency
•Longer battery life
•Best to works with optional Hyper Ground Wire System

seems interesting, but i don't know enough about electrical systems in cars to know whether those systems are all they are advertised to be. hopefully someone around here does!

I am not sure with Toyota's, but Jeep Cherokee's benefited greatly and was a preferred upgrade. They had minimum ground wiring and many praised doing this. I never had a problem, but didn't mud around like many.

I still feel if you upgrade the power side of your system the ground side should be done as well. Many electrical problems are caused by faulty or inadequate grounds. I hope the Toyota's don't "need" this though.

why dont you try to reground the battery first and see if you notice anything? use maybe a 1/0 gauge from the battery to the factory
ground bolt.

A lot of the other products they show on their site seem to be pure crap. ^x2 for just trying a basic aftermarket ground wire system.
