Which will yield better results?

Well...first off I'm new here so I'd like to say hey. Second, my mods are in my sig. I'm looking to do another "phase," either JLT CAI, Accufab 75mm TB and plenum, or doing an electric H2O pump. My questions is which will net more power(anyone wanna render a number? or experience?) and primarily more throttle response/part throttle and mid range power (fun factor as I like to call it)? Also, will the intake mods (will be done as a package) require a retune? PS. if anyone else has any other suggestions let me know, I'm open to any accept UD Pulleys, as I don't want to deal with the charging and possible cooling issues that could arise from those.

Thanks in advance,

Jason
