Default New Throttle & TPS Sensor Question

So i'm getting a new 52mm BBK & a TPS Sensor my question is if I install these new parts would the TPS sensor flow at .55 to .70 volts at idle or would I have to go get it adjusted when I take it to go get tuned? also whats the best volts at idle and at open throttle?

your stock TPS (or new replacement one) mounts as normal onto the 52mm. VDC blades closed .67 +/- and 4.5 blades full open. You don't need engine running, just key on.

You will swap over the IAC solonoid also. Spray the end of it with some TB (not carb) cleaner and do not push or pull on the pointed end of the IAC.

You do need a tune for the larger TB, especially if you have a automatic
