Just picked up a 99 gt this is my firsf mod engine, problem is there has been an engine swap and no clue if it's a romeo or windsor block also its had cams installed no clue which cam set was installed i do know it has pink injectors which almost makes me want to believe it's from a lincoln or a 03-04 engine anybody have a clue how i can identify what block it is. Also i AM installing 24lb injectors dont need to hear why you want to do that lol just need to know what is the best calibrated maf to get, i know the injectors subject is a touchy just need to know what maf and where i can pick it up other than a bbk because every review I've looked at says they're trash. After i find the maf im gonna order the injectors, sct4 tuner and hopefully they can build a decent tune after some data logging.
24lb injectors

Pink injectors came on 02-04 Mustang GT's with the 4.6L SOHC and are 21# injectors.
Going from 21# to 24# really isn't necessary unless you are adding a power adder. I'd leave the stock MAF as well. It's plenty large for what you are trying to do.

Depends on many things, injectors are sized to hp, at an 80% duty cycle.
And the calculation is different for nA or a power adder car.
nothing tricky here at all, just math.
the maf needs to be sized close to hp as well...
adding a huge maf to a car that does not need it, does more harm than good.
Only so many data points to adjust.
Don lasota has many good books on this very subject...with mod motors maf is calibrated in the tune. Yes the tune, and no place else. And is very important to get that correct.
ford racing has a 80 and a 90 maf that is pretty good, low cost , and easy to tune with.
I use them on my builds.
what ever it is you are doing you should talk with a tuner, these changes are made to support more horsepower, but they do not in themselves produce more hp.
Getting parts like this wrong will do more harm than good.

Also to data log and tune, you will also need stc pro racer software, to go along with that handheld...
