Correct, no good tuning solutions for M2 when using 91
If no access to 93 then add 2-3 gal of e85 (as do most that live in 91 area) to increase octane and you will be good tuning area.

So mix in some E85 with standard 91 and it gives you 93(ish)??? Are there any downsides of using/mixing e85 for the car?
