GM TPS to Ford throttle body

I have a GM (VN commodore) TPS, which i'm trying to adapt to a ford XF 
throttle body. It seems that the ford's butterfly does not pivot as much as 
the GM's, (is this possible?!)

When using the GM TPS the ford throttle body isn't able to turn the TPS 
through it's whole 'range'. I'm judging the start of the TPS range from 
where i can feel the spring start to stretch. After opening the throttle 
butterfly fully, their is still another 20-30 degree's left of rotation in 
the TPS before it reaches the 'end'.

is this 30deg used? or is the TPS return 5volts all along this 'extra' 
30deg.

My main concern is that the ECU won't register WOT when the throttle 
butterfly is fully open.

can this be adjusted in the ECU? (like a WOT throttle voltage)

Thanks.
