If you're asking whether it will bolt-on directly, the answer is no, not even close. They're probably similar in terms of the scaling of airflow to voltage, but on the '94-'97 cars the MAF also housed the IAT sensor whereas on the NB it doesn't, so different connector.
I doubt seriously however that your MAF sensor is at fault if you're only having problems under boost. What is your actual AFR when this happens, and what are you using for fuel control?

well my wideband is reading 10.0 and it only hittin 2lbs and sometimes i can get up to 7 but i cant go full throttle i have to feather it.My check engine light keeps coming on and off.i took out the walborro 255 and 7mgte injectors and put the stocks back in it and it still runnin rich as hell still reading 10.0.it dies at idle cause i loads up on fuel.

WTF, you're using what for the who-now?
WHAT IS YOUR CURRENT FUEL SETUP?!?!
aka: what fuel pump, fuel pressure regulator, axillary fuel pressure regulator, injector size, and fuel pump are you running?
I believe from your half assed english I'm understanding that you're running the stock ECU including MAF, and stock ignition? What's your timing set to?
If you're running uber rich, something's uber wrong. Stop driving the car, NOW!

the connections on the 99MAF and the 94MAF are different. I suspect this is because they're incompatible. You have 2 options at this point - 1: get a lower volume fuel pump, 2: get an aftermarket fuel pressure regulator
If you've got a 255 and the stock '94 fuel pressure regulator, then you're trying to shove a basketball down a golf hole. **** isn't going to happen. The bad effects from this are twofold: first, your fuel system pressure is not regulated at all, fuel pressure at the rail is super high, which means that your injectors are putting substantially more fuel into the cylinders; you obviously know this already. Second, your fuel pump is working itself to death by trying to push much more fuel than your system allows. You'll see increased current load through the electrical path (fuses/relays/etc) and a shorter pump life.
