^^ I think that's pretty close. I've never fully understood how or why it works, but I know it does.
here's a question you guys are having or thinking about it.
Q: does it gain more power???
A: to me it feel the same.
You may gain some power (maybe 1-2 whp) but nothing you'll be able to notice.
The real benefit is the increase in efficiency of the electrical system (brighter lights, louder sound system, etc.).
