It seems like you need a 3rd arm for this but with a little creativity, you don't.
Disconnect the TPS plug.
Set your multimeter to Ohm.
Use the Red Lead on the center pin and the black on either outside pin.
Then using a large-blade screwdriver, turn it slowly one way and then back slowly.
It should register from 100 at rest to 225, wide open. Some aftermarket units may register 250 or more. That doesn't appear to bother the ECU. The thing to watch for is a nice linear/smooth progression up and down as it is turned. If it is smooth and hits the 225 value (or so), you have a winner.
Speaking of screwdrivers...
You can also try this: There is a small screw ( as you likely know ) on your throttle body that is kinda/sorta a curb-idle adjustment. You could try SMALL adjustments either up or down, as I seem to remember after mine was ported, it required a small tweak to prevent surging. Once properly set, you shouldn't have to touch it again.
Good luck.
