JB4 at Altitude

I did some pretty extensive searching and didn't really find what I was looking for but if I missed something just point me in the right direction.

I would like to run Map 2 on my JB4 but up here in Denver (and Laramie, where I go to school) you vant find much other than 91 octane. I just have the DCI and JB4 in, was wondering if you guys have any suggestions on what to do or if its safe to run map 2 at this altitude on 91.
