Your experiencing detonation. See the latest Aquila ASB calling for new exhaust. We maintain two AT-01-100 and both engines have detonated multiple times although the club runs on AVGAS. New exhaust for less back pressure at 156/2.72 jetting cures this. 

We also installed EGT under CSTAN

we also have installed latest exhaust, but using MOGAS we still had another event with partial power loss... so you mean, using AVGAS, it should work?
