TT alky if running 93octane comes base at 23/20 timing , only add more as you tune and are certain its not knocking
ive run 27/24 timing in the 87 (all i could get from that chip) and usually run 26/25 in the 86, but for you start at 23/20 , tune with fuel for no knock as you increase boost, dont be bound to a number on SM for o2 as those suck but for you Id suggest 800s atleast , best way to tune is AFR and watch egt , then once you reach your target boost if desired you can lean it out using highest mph as your optimum setting and watching egt , then after all that if desired start adding timing keeping a very careful watch for knock at shifts and for any creeping up through the gears all the while your tuning (get a logger before playing with timing)
