Diagnosis for C4 Please Help!

So basically, I replaced my vacuum modulator, replaced the hose to the intake manifold, and it shifts great now. Only thing is, once it gets to about 45 mph, regardless of what gear it's in (even in 3rd) it makes a kind of whining noise, it's a loud high pitched noise, and the noise only sounds when I press on the gas pedal. It happens as soon as I press down the pedal like at all, even before the engine starts to make the infamous glugging sound that the 200 L6 3.3L Mustang engine makes (I love that sound). Anyways, what could it be? how can I fix it? Thanks guys. Could this be an engine problem? I will put it in both forums.
