Can I run 89? I am on a tuner but I havent advanced the timing or messed with my fuel trims, Will I be safe running 89 octane? I probabaly will have to go to 93 when I start to use hp tuners and start screwing with timing and fuel curves.

Hot Florida air + lower than suggested octane level = begging for detonation IMO
Just add heavy rush hours and lots of engine load, and you should definitely be hearing some wholesome screeching goodness

thats why I asked because I wasnt sure if it was safe or not.
