The throttle bodies are fairly straightforward to balance, although a pair of vacuum gauges are a very good idea - you can get an approximation by something like a 3mm drill bit to set the butterflies on each throttle body, however that is really rudimentary.
See here for a useful thread: Balancing throttle bodies
The TPS however, a thing I’ve left alone, as adjustment isn’t purely ‘mechanical’, it’s like a stepper-motor in reverse, so it incrementally gives a higher resistance value, not linear. Thus far mine has (thankfully) behaved itself.
