Talked to Jack today and he advised going back to the standard 92 map, and running some 3rd gear pulls on the 92 map compared to the 89 map. See which is faster and go from there. For whatever reason, my car did not like the fuel + map.

I need to take my car in for tail light leak before I install my unichip but here is my 2 cents:
Not entirely sure how close Jack (or whoever tuned for him) cut this for the octane rating but I would recommend trying 89 Fuel ~ Timing + or 92 Fuel ~ Timing -. It will bring you a little closer to the optimal power point for 91 octane fuel. once you decide what timing set up the car likes then work on lean/rich for burn rates. IMO the combustion point should be your first target to achieve. In an ideal world i think you want a AFR of 11.5 to 13.0 at WOT (not sure if you have the Flux or if it can even monitor this
)
happy tuning!
Note: I am not a professional tuner just an enthusiast that does a little homework from time to time
