I've read that 9 times out of 10 your rear primary injector will not fire with the N374.

The story is that the N374 will usually not work with a swapped car but usually will work with an original Turbo.

Some success is had with N374's that were chipped in Japan, Knightsports, etc.

Pocketlogger will chip the N374, but I don't think anyone has posted up that the chipped unit will work for sure on the NA swap.
