Default 78mm bbk throttle body non supercharged but modded 99 GT HELP!!!!

i have a bbk cold air intake, bbk tuned headers, bbk underdrive pullys, catless x-pipe, straight pipes, and a performance chip, stage 3 comp cams.. this next summer i am going to be putting a supercharger in my baby. but right now i am trying to get it all preped for it. but i dont want to put something on that is going to make me lose power or make me slow at the start. and i am not sure if putting the 78mm on now without the supercharger if it will hurt me or not and i just wont gain from it right now. i am also installing a ford racing performance improvement intake manifold along with the bbk 78mm throttlebody. so i guess my question is with what i have done so far will i be ok installing the intake manifold and the 78mm throttle body right now before i put on the supercharger this coming summer. or will doing this hurt me until i install the supercharger. and im sure if it doesnt hurt then i can expect to only see minimal gain if i notice anything at all right now. any help will be awesome guys thanks.

The 78mm tb/plenum will be fine on a NA engine. You will gain a little hp but no more than a 70 or 75mm tb would.

Yeah, I just dropped a 78mm tb/plenum into my mustang, and I basically have the exact same mods done to mine (except for the cams)! I noticed a little better response and power, so for you, I'm sure it would be just fine due to you having cams.
