If you action the accelerator pedal to pull the throttle lever exactly the same amount as the cruise control does then you'll get exactly the same reading.

Personally, I don't see any advantage to having the TPS reading in %. If you change it to volts in the Ecutalk options, you can then check if it's correctly adjusted to factory spec.
So if I’m at idle it shows 0%, foot flat it shows 99%, personally I find it easier than volts.
So going up a hill with cruise on, the tps won’t show more than 73% or roughy 3/4 throttle so there’s still a bit to go but the cruise won’t allow it to go that high, if I put my foot down it’ll maintain that speed no worries.
So why won’t the cruise control allow the throttle position to go above 3/4 throttle?
