I have that exact kit. It looks good for engine dress up and adds more sufficient means of travel for ground current. Before when I would step on the gas my head lights would get slightly brighter, now they just stay that way. Like all the power is getting channeled where it needs to be. As far as HP. Not really...it accelerates better, but that doesn't mean more pwr. I wouldn't buy it, but I had a gift certificate and wanted to try it. So what the hell right? I wasn't paying for it.
