91 Octane minimum is the requirement for boosting of any kind. If you typically find yourself short on cash by the end of the week and having to scrimp on gas by getting the cheapest you can (87 Octane) just to get to work, boosting is not for you.
Boost puts extra pressure in the cylinders, and can cause premature detonation from heat/combustion. The only way to reduce or remove detonation with boost is by octane increase. I would not count on putting "off-the-shelf" ocatane boosters into the tank to compensate, because that's like playing octane-roulette.
If you don't plan on being able to run 91 minimum all the time, every time, then I wouldn't even consider boosting, or even a hot N/A build for that matter.
