b16 bolt on with gsr cams, start with what timing

[abitavenger]

I have a b16 and it is tuned pretty well as it sits on hondata s300v3 and I have some gsr cams laying around collecting dust so i figured why not throw them into the b16?! I know its not much of a difference I just want to expand my tuning knowledge and give myself a small challenge.

My question is should I start with a b16 fuel map and overlay gsr timing values into the b16 map? or just use the b16 basemap? any suggestions?
