CH Throttle Quadrant - throttles will not advance toget...

Anyone with the CH TQ have this problem:I calibrate it, but no matter what I do, the throttles don't advance evenly. What I mean is if I move two throttles up at the exact same position, I get different amounts of thrust. It is very noticable for example in the 3 engine Dreamfleet 727. I get noticable differences in fuel flow and EPR in the different engines and tanks (it happens in other planes too, so it is no issue with the 727). I can see the problem right in the calibration screen in the CH Control Manager, so it isn't an fs2004 calibration issue. I have all the axis set at the same sensitivity and null zones (max sensitive and no null zones). I also set up each axis in FSUIPC (payware). Can someone with the CH TQ go into the CH Control Manager and move all the throttles up to around 2/3 of the way up, and see if each indicator is relatively even?
