I know I read it somewhere in here but I cant find it to hell....

I just pickup another Q45 Throttle body, Got it installed on my car and Im looking at my MAFT PRO TPS voltage without the car running and Its a .59v, With the car running its veries from .48v to .49v?

I read somewhere that you need to Adjust the TPS to .38v but it didnt specify if this is when the car is running or not running, also If the Q45 TPS is set from the factory at the above settings, why do we have to re-adjust it for our cars.

So there is 2 Questions.....

Do TPS Adjustment with car on or off and to what Voltage?
Why do you have to Re-adjust the Q45 TPS if its already factory set?

This is all I need to finish. Thanks
