Engine timing

ms109? Aftermarket ecm? Need just a smidgen more info.
i just have the bama chip but ive done alot of small mods i have ported head and intake both gt40 xe266hr cam ,comp timing set gears,24 pound injectors ,roller rockers 1.6,aluminum radiator with duel 12 inch fans ,aluminum drive shaft .tko tremetic 600 with the .82 fith gear .and mcloud rxt duel friction cluch
 
Not sure how chipped ecms are programmed in regards to timing but I'd say start at 12° and then add a degree at a time up till 14° as long as it does not ping. I think any more than that will likely not get you any gains. Thats is just the opinion of an old guy,
