so the heat exchanger is useless too? yeah, i went pretty nuts adding all that stuff, glad you guys are catching everything. thanks, again I ask though, if not for horsepower gain, why not add a single blade tb if only for throttle response? just like adding an exhaust only for sound...ya know? i suppose the response to that will be "its your money and your truck, so if you wanna waste it thats up to you" :bash: heres a question, will the mods suggested above change throttle response to a point adding a tb would make it unnoticeable or does anyone really know? i would assume thats a tough one to answer, except for people who just have those mods if they could tell me about the difference they felt.dirtchicken said:Do not waste your money on a plenum, throttle body, or heat exchanger. Use it elsewhere.
