The lexus afm will work, but your car wil run lean and youll FRY your motor without the 550s, and you will need the safc dyno tuned once you install it or you will also fry your motor. And what it sounds like you have is a boost/intake leak. How do you know its a bad maf? Make a cap for the front of your turbo that you can put a car tire air valve into, and pump the system up to about 15 psi and listen for leaks. have a friend look at the boost gauge too so you dont over pressurize it.

that doesnt mean the afm is bad, just that the afm reading is incorrect, which can be caused by all that stuff i said or maybe a bad maf, but check the things that are free first.
