Help: APR Stage I... should I go 91 Octane or 93 Octane?
Both grades are easily available around here, but in other areas 93 can be tough to find. Going with the 91 would give me wider coverage with no risk of engine ping. The difference in hp and torque are marginal. Thoughts?

Get 93 and stock...
Why bother with the 91? I did the same for the same reasons you did but I never once used the 91 octane. If its really a problem switch back to stock 
Save yourself the money and just go for 93.
