For some reading your request it will help them if you give the type of joystick currently being used on your PC.
bustr is correct! what type of stick do you use
also, I can not help you much for scaling a "joustick".... I do not teach or help people with "jousting"

( just joking about your spelling )
what or how do you have your scaling set up currently would be of help also..... ( if possible taking screenshot pics and posting them here for each axis would be of help possibly )
you can also do a search on the messageboards, regarding this problem........ search for "Joystick Scaling" and I am sure you will find numerous threads regarding proper & good ways of setting your scaling.....
hope this helps
