Replacement throttle bodies need calibrating with Vida.
I would therefore be using Vida on the existing throttle body to read out the current position data and run a calibration on the current one just in case it has gone slightly out of whack. It's not impossible that no replacement is necessary so always best to check to avoid wrong and sometimes expensive guesses.

Same with MAF data. You can graph everything you need to view its operation.

Dice and Vida will also be able to read all of the other modules on the car and the built in workshop manual and parts catalogue will guide you through doing your own repairs and potentially save a fortune.
