Well after another month of neglecting the xfire I'm going to finish my exhaust. I'll finally have a proper place to work on it Monday. I did drive it today after doing some small mods(catch can, cooler thermostat, recirculated BOV, first oil change). At only 10#'s of boost I'm pretty sure it will destroy any limited crossfire. This is going to get very interesting when the boost gets turned up to 20+#'s.
