throttle body or mass air flow sensor?

Im looking to add another aftermarket part to my mustang. I already have a cold air intake. i was thinking of going with a throttle body or a mass air flow sensor. anyone have recommendations on which one to go with and by which company. any info. is appreciated, thnx.
 
Accufab is considered the best there is for throttle bodies. A 65mm would work or perhaps a 70mm depending on the rest of your plans. As for MAF, Pro-M makes good ones (bullet for example) - they are not easily recalibrated if you change your injectors - you have to send it back to the company for recalibration for a fee. C&L make good ones too - partshopper.com has a 76mm on sale for $185. They are easier to recalibrate. Would seem to make more sense to get the TB unless you know you are staying with 19 pounders.
