Do I need a bigger TB and MAF?

[mooktank]

my mods are in my sig. I just got to thinking about my TB MAF and filter which are all stock besides a K&N filter in the stock airbox. Based on my heads and intake do you guys think i need to upgrade my TB MAF and filter? Im thinking of going to a blower soon so I dont know. Im also not too big on money right now and the car runs pretty well. Im just wondering if these parts are choking me up.

its not in my sig but i have a stock intake ported and polished.

A throttle body will help if your intake is opened up for it but will give you small results. A bigger mass air will help a lot. I suggust going with a 65 mm T/B and Pro-M 80.
