My SS runs very well with straight 93 fuel on Map 2. As we have observed, logs show that octane is a significant factor with higher boost levels on the engine. With a E30 blend (1:4 E85 / 93) I can run with Map5 (+6) and the logs are just fine. A bit more E85 to push the blend towards a E35/40 and Map7 is obtainable w/o timing issues. Your logs will tell the tail - feel free to post them here for the group to comment.
