Describe the bug
When transferring power from the mining dimension the power that went into the system was only 644000 even though 1200000 was supplied to flux system

To Reproduce
make the mining dimension portal
build power source
attach flux plug
set input to max
return to overworld
look at flux controller
find power output below provided power

Expected behavior
all the power given to the flux plug sent to other dimension

Got a work around not really ideal though
If you add Draconic Evolution the power system they use seem to get sound the transfer problem
connecting the max power crystal to the power source then to the plug seems to let all the power enter the system
think their power system can transfer 2.1 billion RF a tick not sure
not though dimensions though ;p
Screenshots
If applicable, add screenshots to help explain your problem.

There are no imposed limits on Flux Network's side so I suspect the other blocks you are using only allow a certain amount of transfer per tick. If it works with Draconic which has no limits whatsoever this would make me think this is definitely a limit with the other cables / blocks you are using.
