Max base timing advance for 1990 Ford Bronco II 2.9

[A4LD_Nghtme]

Hey there. I was wondering if the 2.9 can handle anything more than the 12 degrees base advance for a little more power? I currently have it set back to the stock 10 degrees advance so that I was able to pass CA smog and now that i have passed i was about to set it back to 12 but wanted to know if 13, 14 or maybe even 15 are possible? It may be a stupid question but I wouldn't know without asking. I live in high altitude and read somewhere that 14 is good for high altitude but it was not 2.9 specific. Any information is much appreciated!

I had mine sat higher then 12 for a while, i think 14 or so IIRC. I had to run 93 so it didnt ping and i had no power difference between that and being set at 10 where it is now
