13b semi PP

I have a 13b semi pp with s4 high compression rotors and a S362sxe .91 turbo. 93 octane currently with wastgate spring at 14psi. I have the car up and running, idle and my base fuel map seem pretty close so far. I will be starting road tuning here soon. I built a linear ignition map to get me started but can't seem to find any good data to adjust my timing numbers to be safe to start with being a high compression turbo setup. I have found plenty of safe maps for low compression cars but what would be a safe timing map to start with for a street tune.
