The TPS is "fixed position"
You would have to elongate the holes to give it adjustability. There is also little material to work with so if you try it. BE CAREFULL.
I still do not see an up side to this mod.
OBD-II uses whatever voltage it gets from the TPS at full close to indicate such. It varies from car to car already some. So why would changing it affect any settings?
Also as I have stated before. It WILL NOT affect WOT settings.
Basically you will dump more fuel at part throttle (cruising) and kill your gas mileage, but gain no real performance benefits from it.
This is also why OBD-II will eventually tune it out. It monitors both short and long term fuel trim!
