Looked around the site but didn't/couldn't find anything specific to this question:

What is the the desired voltage on the TPS of the EJ25 in a '97 OB? From a previous vehicle (NOT a Subie) this could be adjusted to .75v to improve throttle response.

It's supposed to be set at a half volt plus or minus a tenth for '00 & '02 (sorry no data for '97). The ECU uses this voltage threshold to determine and toggle between idle & part throttle modes (no physical idle switch).

 

There's no performance gains in moving it.
