Well I'm using everything stock.(even the second cat and stock exhaust)
I just dropped off the car bone stock except for the intake I had on it, and picked it up BOOSTED!!! This thing pulls like a beast. I was hitting 130 before I knew it, and had to let off cause of traffic.
as far as specs your gonna have to get with Juan from Hiboost about that but he included some top notch stuff like a TurboXS boost controller, a bypass valve, Stainless steel lines, and a FMIC that he has tested to be the most efficient on the market (bigger isnt always better) Its basically the same setup as th Mazda3 kit except he uses Xcal2 for the Focus. We believe that with a 2.5 exhaust we should expect at least 220 with cat, and 230 w/o cat.
