First thing I have to say I arived here thinking this was just another Website, but to my surprise this Website has everything you would want to know about your Mustang and someone else's. Very nicely done!

But my question's are: (1) What is the Factory size of my Stock Fuel Injectors in my 2003 Mustang GT 4.6 and are they 2 hole or 4 hole out put, 4 being high flow I take it.
(2) What is the size of my Mass Air Flow Sensor, 70MM 75MM?
(3) What is the size of my Throttle Body

No body seems to make this information easy to find.

injectors are 19 #
MAF is 80mm
TB is 65mm

I don't know about the 2 or 4 hole thing though, sorry.

If I have Factory Fuel Injectors and there 19lbs. aren't they usually Orange and if so are the Factory one's Pink.

they are a reddish pink.

19lbs, never heard of two hole but yours are probably 4hole, there not for high output really, just make a better spray pattern--check out fordfuelinjection.com/index.htm

I thought those numbers were way off, sounded so big. A few friends have corrected me that they come 80mm maf and 62 TB. So I stand corrected.

For '02's and up. My injectors say 19# on them.

[traveler08062]

Yes unfortantly I have Pink, bright Pink and there Factory because I bought Her new in 2003 (GT) I just can't see them putting a higher Injector then the 19lbs. and I haven't heard anything about 21lbs, were they special for that certain year. Did all 1999 to 2003 Mustangs have 19lbs. Fuel Injectors Factory?

Yes, but he's talking about a 2003........03 GTs came with 2 different injector sizes.....reddish-pink are 21lb and pale pink are 23lb.

To Eye of the Storm I thank you, Now I take it they stopped the normal 19lbs. Injectors in 2002 and why did they go to the different one's in 2003? I have the Pale Pink so I have the 23lbs., but if I already have 23lbs. Injectors what is the next step without going extreme by adding things like another Pump and gage's? Now the 1999 to 2002 GT's have a Fuel Pressure at Idle is between 35 to 50lbs., is this enuff Pressure to run a bigger Injector, ofcourse matching them with the proper Mass Air Flow Sensor? And when should I consider stepping up the Pressure?
