Basically, there is a three stage intake manifold that has a few valves in it and an ECU tune to control the motor with the new IM. at least from what i could tell.
I don't think it'll be very cheap, but I think a 265 hp 128 would be pretty sick. especially when you add a few other 130 series bolt ons to kind of sneak the power up a little more.
