Pro Flo 4 Timing

I've got a question myself. Is anyone running a CDI box? I'm looking at an 8hp70 swap and tq management is key to trans life.

The box that allows the trans to work without seeing all the rest of the computers in the car has an output that is pulled low when the transmission wants to see reduced torque.

Other aftermarket ecus have timing retard options for nitrous or general inputs that can trigger whatever you want.

I'm considering a CDI box with a nitrous retard function, not using any of the timing or rpm controls except the nitrous input to pull timing at shifts (100-300ms).

I know that another user in the Edelbrock forums had success limiting rpm using the 2-step function on one, so I'm hopeful, but I was hoping someone here could chime in.
