Wondering if the T-ReX v.2 cam will cause too little vacuum at low throttle for a TH400 to shift smoothly. Any opinions?

Talked to a friend that knows transmissions. Answer is yes, it can work fine. Vacuum modulator should be able to work to about 250 intake duration. Just need to fine tune the modulator and governor to do what I want for my case.
