DOes it really improve as much as it say it does if any1 out there has it??

 

it works in the sense of better idle, better electrical flow,speakers had been known to sound better, but it does not give you more HP.

you'll need a battery with an extra negative ground, I dont know if any have managed to use this without an optima or other battery with extra negative and positive connections (you'd just need neg).

some have even made this themselves and saved even more money.
