It would be neat if we could customize a bit more the energy values for each machine and cables and tiers:

• It would be great to be able to choose how many EU/t each machine consumes
• How many EU/t each machine can input
• How many EU/t each cable can transfer
• How many EU/t each generator generates
• What is the tier of each machine, generator and cable
  Thank you in advance! TechReborn is really getting better and better!

How many EU/t each machine can input - already done.
It would be great to be able to choose how many EU/t each machine consumes - done via recipes
How many EU/t each generator generates - done via recipes

Tier calculates automatically based on input or output rate.

I could be wrong. As for me it looks like the only missing thing is ability to change transfer rate for cables. If not may I ask you to provide examples, please?

You're actually right. Can I ask for a config option to choose how many EU storage units store (batbox, mfe, mfsu, aesu, idsu) and what is their output rate?
