I have a 2002 F-250 5.4 i have a few mods to it already like cold air intake, full exhaust with high flow cats, throttle body spacer and also superchips tuner. i was wondering if going with a set of underdrive pullys is going to give me any real noticable amount of power

you might get a slight performance gain. i would throw away the spacer and then save money for a custom tune. that would put in the power on the ford.

i am not trying to make this thing a rocket ship but i would like a little more power cause with 6 inches of lift and right now i have 33s on it but come spring 36s are going on it im going to need that little extra power to spin them

oh yay i perfectly understand. but as there is the thing about the pullies that they do slow down the water pump as well. i think a custom tune is going to net you the very best results in the grand picture.
