Could it be the sound you are using?
The more depth a sound has, the more momentum it seems to have as the pitch goes up. Also, you can introduce LFOs into the rise itself to add some more tension, just to reduce that stability or monotone feeling as the pitch gets high.
Although I'm sure there something else going on that has a more fundamental cause. I personally don't use pitch rises, so I couldn't tell you. Sorry!
