I believe that there are only about 4 of us on this forum that speak from actual knowledge/experience versus those that have read something or made up their mind that they know better. The hypervoltage system will do NO harm....I am coming up on 3 years since mine has been installed. While this has been discussed in several different threads, with just as much BS, you can go to the link below and see why I installed it and the results that I experienced:

While I am not trying to start this whole peeing contest all over again, if you want to read through all 60 some posts of the above thread, those of us that have actually installed it are pleased with the results. I doubt that there is any HP/Torque gains to be had from it as the write-ups suggest. But I can attest to the steadier voltage.
