which AP map for my setup?

[DrJones]

Hi,

I have a canadian 2008 MS3 with the following mods:

- CPE CAI
- Test Pipe
- ETS TMIC 3.25

I know that the good map (v1.03) seems to be:
- stage 2 - MSCAI- TMIC-93


The problem is that 93 octane is not available in my region. So should I run
stage 2 - MSCAI- FMIC-91 ? or just stage 2 - MSCAI-91

Thanks for your answer.
