A-Trim question!

[TransAm86]

I have done some reasearch in the posts about adding a supercharger to a speed density car. I came to the conclusion that a A-Trim @ 6psi could be ran on SD. But the problem is that the MAP sensor can only read vaccum. Now what is the way around that? The fmu included in the kit will manage to supply more fuel? But I have also been told that the max injector size on SD is #19. Should I expect major problems? I have read that idle might be a problem? I dont care if its sloppy or if it goes up and down all the time. But does "idle problems" mean that the car will keep on stalling? I remember someone saying is car was "surging" when he stepped on it; what does that mean?

Thanks,

Nik
