Do you have a boost guage? I believe the normal peak boost is about 9-10 psi for the m90. It's dangerous to stare at your guage when going WOT with a blower, but 3rd gear shouldnt be too bad since I don't even spin my tires in 3rd when they're warmed up.
If yours is about 9psi, then i'd guestimate 400-450whp, depending on boost and health of motor.
Oh, and post pics.

I believe the most important one is A/F guage since that determines if your motor goes ka-boom, then a boost guage just so you know about how much hp you're putting down, then a fuel pressure guage. Then last but not least, a knock guage would be more insurance (never seen these but someone made a topic about them yesterday)
Guages and pods can be expensive but it's not only safety but also can look cool.
No pics? Imaginary car?

No m90 is making 9-10 psi......I wish. 5 psi is normal. Depending on your other mods you should be putting down around 375 ish rwhp if stock. Adding a cai, longtubes, smaller pulley and cams will improve it. All of those of course would need a new tune.

No need for gauges on the M90....you're not making enough boost to be concerned, just enjoy it!
Oh, and try punctuation...doesn't this read easier?

Hey guys, new car, just got it. I was wondering do you have any idea what my 2007 mustang gt, m90 roushcharged, mustang with off road x pipe, and flow master 44s would have?

Agree with 808muscle, 5 psi boost with a Roushcharged M90 and stock pulley. Horsepower numbers maybe slightly lower at @355-365.
Long tube headers, pulley and tune will help horsepower numbers. A one piece driveshaft will help with torque.
Put it on a dyno for the real data.
