Scarceller, No knock sensor but I
only altered my idle and partial throttle (up to 0 psi boost) values. Anything above .05 bar runs on my normal boost map (that has been to the dyno). The 993 values at idle and partial throttle are actually more conservative than what I've been running for about 3 years with no knock. I'm running 8.0 to 1 compression before the boost cuts in so no worries there. I'm also running a full bay intercooler and haven't run into any knock problems at the advance levels and plug heat ranges I've been running. By the way, many thanks for finding and uploading the 993 values. You're local to the Providence area, right? We should meet for coffee when the ice thaws (July?).

Does flame front move quicker in a turbo cyl? If so you may want to back off on those ign values. The best way to know for sure is dyno testing.
Good luck and glad the 993 data helped.
