I searched, and I don't think this has been covered before. I just installed my FC throttle body. My first thoughts were "wow i've got a butt-load of throttle response!" But later on it seems like it falls off at high speeds. It doesn't seem to pull as hard as it used to from 50mph on. Has anyone else noticed this? I know I don't have a vacuum leak and the car has had a couple of tanks of gas in it to re-learn itself.

I guess what i'm asking is if it's normal?

the tb doesn't really add any hp. the throttle response you feel at lower speeds/rpms is about the only thing it is good for. for an NA car you are probably only seeing 2whp tops. so yeah, it's normal.
