well that sucks... all these mods and 160 hp to the wheels. id imageine the stock 2.5L duratech with intake/headers/exhaust would pull those numbers even on an ATX if its 170 crank stock.... With these mods i was hoping toward 185/185 and with nitrous 230/230... i guess its just not possible for us cougar owners... maybe id have to go more indepth and get the heads pnped? but i wouldnt mind, runnning open headers all the time
