So that is 32 degrees yes???
What boost is that at?
What compresion ratio ?
All these things will effect the answer

32 degrees is a lot for that boost on 93 USA, but if it lives at that I would go to 37
Any more than that shouldnt make a huge amount of difference any way.
You could try a quick test at 40 but I reakon it wound not be worth even 100 rpm gain.
Just my opinion

That is what I meant "using Q 16"
I havent had a lot to do with Q16 so I am reluctant to predict anything too agressive
You should be fine at 37 degrees useing Q16 and any more than that wont make that much difference any way.
The only way for me to be sure is fit a knock system and test.
