Got it all wired up, and it works, kinda. When you start to accelerate, the light comes on and gets brighter, just like it should, and you can tell there is more power. But then after the rpms shoot it, somewhere around 2500, the light goes off and no more extra power. Does this every time at around the same rpm, on either setting on the box, execpt off. Does this with the smarty on any setting and without the smarty. So what gives, bad box? Weak VP44? Now i'm worried...My connections are good and secure, the power wire is tapped into the right fuse, so I'm thinking it might be a bad box. The other thing is when you first turn the key on, before you start it, the light is supposed to flash a few times, but it doesn't.
