I don't trust the manufacturers... how much REAL horse am I getting?

Hey guys...

I have an 06 gt and im in the middle of converting it to
a stage 2 roush. I've added 4 things and am wondering
what the REAL amount of additional hp i've added to it.

Roush exhaust, roush cold air intake, bbk 62mm throttle
body, and a ram air hood from trufiber.

Overall "they" tell me an additional combined 40 ish hp
but I'm not fully convinced.

What do you think?

Thanks!

. Other than that its pretty much all speculation. For future reference, don't waste the money on a TB until you're in the 500+ Rwhp range IMO. My car has over 130hp more than stock, and the stock TB still seems to be doing fine.
