PS this data was from a very respected tuner on this board and judging from all conversions i done this feels the quickest so i guess if a std engine can dyno at 430bhp on 4 greys @ 1.7bar then this with a higher boost and spike and ported head cams etc etc regardless of a safer ignition curve it will still be around 430 real time in car....yes it could be tweaked to optimim but why bother...cossie engines are time bombs as it is....nothing wrong with having a bit more safety measures!
