A) should be equal length (close to it)
B)should be placed xx inches away from any major turns
C) at least 6 inches away from the TB's ( not sure about this one)

Yes the readings will be more accurate, however, they will still be far off from ideal. Since the intake manifold combines the two throttles into one input, The fueling for each bank will be error prone since the car still thinks each maf is feeding the engine using the OE design.
Aside from the balance issue, there’s the problem of uneven flow between banks which can appear under certain conditions.
In addition, with uprev it will not be possible to implement any custom code to optimize the performance such as dynamic timing adjustments based on load or various failsafes to prevent engine damage. A properly ecutek tuned SC kit will maintain perfect AFRs vs target and a smooth consistent engine load when compared to MAF configured vehicle on uprev.
