Default N2O on 93 3800sc

what is the largest amount anyone here has ran with stock timing?
I know Zex recommends on 55 shot , but that is also only what they recommend on the 4cyl hondas. I kinda wanted to go up to the 75 but kind of unsure about with stock timing. I went 2 ranges colder on plugs and have a CAI. I have the 95 70mm tb and sc with the smaller 93 pulley. Peaks around 10psi of boost.

I am already running a 55 wet shot , I dont have a problem running lean not even a consideration. I have a mini afc2.0 ( if not already tossed in trash can ..... it was toast car got to where it would not run with it ) Im just worried about detonation with a 75 shot timing is my concern.
