i've google and search on s2ki here , not much came up besides its own dyno test (5whp gain), has anyone try this product? any comment of this product? how much gas mileage will it improve?

I personally don't believe it, it could be accurate but I'm not buying the ad. We've seen high performance coil on plugs dyno tested and making about 2 whp on a stock setup, about 6 whp on a boosted setup, this system just alters the voltage into the stock system so I wouldn't expect it to make more power than totally upgraded COPs. I like the idea of ugrading the electrical side of things, and I could see something like this helping by a couple hp at best but I wouldn't expect any more than that IMO.

 

Yea right, get one of these tooooo.
