Could I Have Lost Power?

Hi, I just recently updated my stock air intake system to a cold air fenderwell kit and a 75 mm MAF. I have the stock intake manifold. It seemed pretty quick after these mods, but then I added a 65 mm Throttle Body. Maybe I'm just used to the new power, but would the TB make my car slower? Is it too big for the stock manifold?
