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.
