Post a pic of the sensor. Is it from the new TB or the old? If it has metal sleeves in it, press them out to make the holes bigger, then put washers under the heads of the screws. That makes a bigger hole to let you move it around. You have to get the low and high ends in at the same time. It can be tricky, and is easier to do off the car.

Where in the throw does it first read 0 and 5%?

I'm thinking the TPS values may be different and you might need to program them into your PCM for it to recognize.

My concern is if you bore too much.. you might get the 100% at WOT and have 5-10% at idle. Which would end up equally bad.

We always measure voltage through the sensor which is then converted to % of throttle. Somehow I think we could measure resistance throught the sensor. Maybe check the two and see if you have a large difference.
