MAF and Throttle body Questions

Hi everyone,
I am adding on some things to my setup and wanted to ask you all a couple of questions. I have a 2000GT that I have a Paxton Supercharger with about 8-10psi currently. I recently installed new gears (3.73 ratio) and am about to install the Paxton Air to Air Intercooler as well. I am going to the next smaller pulley size (3.3?)and am installing a bypass valve as well.

My questions are about my throttle body and MAF Meter. I have the stock throttle body on my car, and the stock MAF Meter as well.

I am going to be doing a retune and wondered if for my application it would be smart to upgrade the throttle body and MAF now. Currently have about 375rwhp..not exactly sure how much the Intercooler/pulley install will give me, but wasnt' sure if I was outgrowing the throttle body and MAF meter? Any help, suggestions are greatly appreciated. I was thinking of doing the 90mm Lightning MAF Meter , and not doing any changes with the throttle body.

What do you all think?

Thanks,
Mike
