Unhappy Is the sc400 maf compatable??? HELP.

My Mass Air Flow just failed and I cant drive me car. It just blows black smoke and wont go past 1800 rpm. I need a new MAF so I am gonna buy one from ebay. They have the stock one and the sc300 MAF which when combined with 550cc injectors and a AFC is supposed to give me 25% more fuel/air. Could I put this on my car that is running 10 psi?? I have stock injectors and no AFC. Would my car run ok untill I got the AFC and 550cc injectors?? I really need to know because I need this part ASAP. I dont know How I AM GETTING TO SCHOOL TOMMOROW, I hope something comes up .

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.
