What afr is best for making peak power the sert manual says 12.5 but ive always thought 13.2 was suppose to be best ???

Without a dyno and a sniffer, the numbers in your SERT table are meaningless.
You tune to peak HP and whatever it's at then is what is best for your setup.

I was refering to the sert manual not the maps I went from woods tw400g's to tman 650's then back to woods tw408g cams . It was running mid to high 13's on the afr for the 400's and the 650's now its in the 12.5 area and its lost power over the entire rpm range as compared to both the other cams

Was it dyno tuned after each change?

12.5 is too lean
