Nah, he's currently still active. He's not sure when he's pulling the plug.

Evans is officially done tuning street cars which really sucks.

Well anyway, my throttle body was sent out to maxbore for boring/venturi service, currently building a 3.5" CAI to replace my V2, and port matching my IM when the throttle returns before getting tuned.

Bumping an old thread. Any updates on the tune ? would really like to see what you make with this header combo.

My boy ended up giving me his Haltech tune he got from Jeff Evans our mods are pretty much the exact same as far as diameters go and engine compression. Haven't actually driven the car with the tune yet. In all honesty I can't see it being that far off from the likes of most other setups of similar piping sizes and intake mods. I went the origin route mainly because of the high build quality and ridiculous weight savings. However the design of the Origin header is quite different from off the shelf headers, the runners come so far off the head that you actually have to tilt the engine about 4 inches to install it. That might be reason enough to outperform other brands, but as always we're nickel and diming with an F20C.

Fwiw, there was a noticeable difference in power from just bolting up the origin stuff in stock form.
