Adjusting Catapult Pressure

Hi guys!
I know I've read about it before and I thought it was here in the forum but no luck finding it. So I'll ask the question...
How do you adjust the pressure on the aicarriers catapults? Right now it launches my SB2C darn near vertical about half way down the cat stroke.
Thanks for any help....
