The likelyhood is that the "retuning" of the engine will not result in ONE extra ft-lb. of torque - it'll just result in the torque peak being moved 500 rpm lower. What it really means is that there will be less hp hit high in the rev range, and the torque hit will be the same but will occurr at a lower rpm. This is only speculation, but that's what apparently ALWAYS happens when they "retune" a sport-model for "standard" duty, and it pisses me off.
