BM3 Multimaps Question

[Mayday]

Hi,
I was about to flash multimaps stage 2 using BM3 but I noticed that on each map it uses a different octane levels. In my country, the highest octane level is 91 octane ( 95 RON ). Is there any way to adjust the 4 maps in 91 Octane?
If not, Would a CustomROM request from a tuner could do it?
and one more think, Multimap stage 2 shows that I’m required to have
(high flow downpipe)

But my car mods are
Catless
Full exhaust
Charge pipe
Cold air intake
Don’t you think using Stage 2 91 (AGG) Map which requires full exhaust is better than using Multimap stage 2 which requires only High flow downpipe?

Without a flex fuel sensor multimap does nothing for you.

Flash the 91 stage 2 map of your preference.

You can still use the multimap and just steer clear of the 93 map. Let's say you're in a jam and need to pump lower octane gas temporarily, you could run stock power level map or 91 ACN.
