Can't apply full throttle

I have a problem that's driving me buggy. It feels like I'm only getting about half throttle. I have a new 3 Ghz Dell XPS, XP Pro, using a Radeon 9800 pro 128 mb card, and 2 Ghz of RAM. I had this problem with 2002 and 2004. I've tried two different joysticks, turning down my audio card, changing the joystick settings, using Microsoft knowledge base, and going into Safe Mode and removing listing from the device manager, going into the registry etc, starting the computer with only generic drivers, unplugging the joystick, replugging the joystick, and still no improvement. Any geniuses out there? My life is only at half throttle.

Set the sensitivty on the throttle to full and set the null seting to zero. Also, you can use your mouse to set the on screen throttle to full to make sure that it is the problem.

hit "F4" to go to full throtle, also in vc mode hover the mouse over the throtle (have tool tips enabled") and you can see what the throtle is set at.

Thanks...Was having that prob too...But now all is well.........
