don't bother. I was one of the optimistic guys who thought it might actually gain some power. More guys with autos had good results vs. guys with manuals.

Well, I dynoed with mine and lost 1 rwhp, and gained 4 ft/lbs. All it does for me is make the engine run smooter, give a nicer exhaust note, and let me change the gear ratio, and change the fan temp activation. Thats pretty much it. Money could be better spent elsewhere.
