Good question. I would think 91 would be most practical as such that any "Premium" would be ok at that point.

As from what I understand my 1988 car has a slightly different ECU and Chip to work with the higher compression motor (please correct me if I am wrong).

The computer is the same - the mapping is slightly different to account for the added compression...
Yes, I will have an '88 option.

91 octane. There is only so much to be gained from raising octane in a non-forced-induction motor. Additionally, you can get 91 anywhere in the US, but many places cannot get higher (like here), so setting it up for 91 ensures that it will work anywhere in the US (and most of Europe/ROW).

Yeah, the rating system is a little different for the non-US/Canada people.
95 RON is roughly the same as our 91 AKI.

UPDATE!
Ok, I finally made the dyno. I am quite pleased with the results. FYI, the only mod to my 85NA is the N-Tune, everything else is completely stock down to the cast-iron headers. The dyno really shows what I've felt all along - great gains at every RPM!
Without further ado:
