Well I can help with some basics.. but obviously GT will be the man to talk to..

Lots of FI applications us a map sensor (manifold absolute pressure)... it detects the amount of vacum (or in the case of forced induction boost) and calculates how long or high to open the injectors...

Bar the metric measure of boost... that's why the different efi systems are only compatable upto a certain amount of psi because they cant read any thing over that so the injectors inject enough fuel...

I'm sure LOTS of them can have the map sensor changed to a GM 3bar... but why not just get the one built to be used at that pressure to start with...

As far as dist.less ignition... You don't "need" it... it's just more accurate and allows you to use individual coils instead of a single coil... you could run any highquality msd distributer although you'd make your life easier by getting one with a 6al or the like so you could retard the igntion as the rpms rise (to prevent pre-ignition under boost)...
