A 966 kit with your added stroke will definatly boost the compression to the high zone. I would stop messing with the tuning and sort the detonation out before you end up re-building the whole engine.
I would change the lobe center to 112 degreed with belts at 10 on the old tension guage scale or 180hz on the new tension guage. When setting belt tension make sure the belt your working on is set at tdc with both valves closed . Otherwise the spring resistance gives a false reading. Are you running 98 octane fuel as well ?
If the cams were degreed to 108 with belts at running tension the engines centerline when running will actually be around 104.
