how do you do it?

well are you looking to get rid of the stock VAF (vain air flow meter) and get a actual MAF to increase flow. or get rid of it all together ? and run a MAP and go with a Speed density setup ?

Yup, run a Megasquirt and a pressure sensor. Delete the VAF entirely. You should pick up a few throttle bodies...maybe off a bike with 38-42mm throttle bodies too, with some low-impedance injectors.

how much would it cost to get rid of the stock MAF and I just bought those mustang 4 way fuel injectors. Do I just install them with no other mods.

Why do you want to get rid of the afm, and don't give me the "It,s too restrictive" excuse because it's not, Metric Mechanic makes engines that produce over 180 hp on the stock afm. As far as the four pintle injectors, just install them and the ecu will adjust over a period of time.

First of all it just looks ugly I don't like it 2 I wanna get a nice cold air then 3 some say its air restric and some don't but if it dosnt make a dif I woulnt. Mind I just don't like that big square box in the bay if there's a cheap way of geting rid of it and getting a maf I woul be thankful to know thank you

If you call cheap $500 then yeah you can get rid of it cheap, Oh and don't forget the dyno time and tuning to get the car to run right after you remove it for no extra power gain.

if you wanna delete it change engine! M44 don't have it so big! eventually you can put away all the electronic management and put on 4 motorcycle carbs

It will still require a standalone ecu to control ignition

no , you can leave the stock ignition working while the carbs control injection (i think it work)

you only have to disconnect the injectors and put on the carbs

Well if is not restrictive ill just find a way to relocate the vaf what do u guys think could it work

It would probably look hacked up if you moved it. Its not worth it; it looks just fine if your engine bay is cleaned up.
