Is the Red box APC the equivalent of a tweaked black box APC?

Thanks - Simon.

AFAIK The Red box is the same as the basic tweak for a black box.
ie Change the two resisistors and turn up the pots a bit.

There were different Red boxes though? - more power at high revs due to less boost taper according to the boost graphs I have seen.
