Looks kind of like a gimmick to me. One of those miracle chips that actually doesn't do jack.
As far as performance chips go though, D&D and BlackMagic used to make EFI chips for the older Cat EFI sleds (up until '00 or so). I have a D&D EFI chip and other goodies in my '98 ZR.

A mountain lion roaming the prairie found a bull, killed it and ate the entire bull. With a heavy belly, unable to walk, the lion laid in the tall grass moaning and roaring. Soon a hunter, attracted by the roaring, shot and killed the lion.
Moral: When you're full of bull, keep your mouth shut!
