They are like UPR. They just make cheaper copies of other peoples work. Nothing wrong with capitalism in my book. There are people making good power with the kits. But long term problems and fitment issues from what I keep seeing make me wonder...
I must admit though, even I will go single turbo in the future after I finally toss a rod in this motor and get a built one. I can't see spending the money on a turbo setup on a stock motor and being limited to 400rwhp roughly. I would just as quickly get a Procharger which is cheaper and easy to install and will push more power then the stock motor can handle.
