Does anyone make a grounding kit for the LS1?

The description/definition posted in that thread says,
Automotive electrical and computer systems are designed to tolerate up to 100% noise on its input lines. Meaning, if the ECU is expecting a 12-volt input signal, the signal may vary in the range of 0 to 12 volts. Fluctuations in signal are due to noise in the system. Noise is generated by spark plugs firing, discharges through the tires to the road, alternator turning on/off, etc. In other words, there is a lot of inherent noise an automotive electrical system.
One of the best-proven ways to compensate for noise is with proper grounding.
When measuring a DC (direct current) signal, almost any kind of wire will due. However, when measuring a high frequency input (i.e. the mass air flow sensor or the air/fuel mixture sensor) it is necessary to run a ground wire in parallel with your signal. The engine grounding/earthing kit provides grounding along side each signal wire.
The 350Z Engine Grounding/Earthing Kit allows for cleaner data transfer to the ECU. The result is more accurate measurements by the ECU and therefore more accurate performance, smoother idle and acceleration.

I've gained a smoother idle, and a smoother power band from cruise to redline in a few imports. This on the factory ECU, as well as aftermarket standalone ECU's.
I've read some of the write-ups, and I'm a cheap bastard and was skeptical. I instead just picked up some standard 10ga wire(not the car stereo grade stuff) and normal eyelet crimps to make my own grounding system.
I added a few from the block to the body (about 4), the battery to the body(just a single 10ga connection), and thats it.
I also saw the voltage reading based on my HKS Turbo Timer go up about 0.2V. Interesting change to me at least....
