Ignition advance help

[Volvo_runs_on_boost]

To give some background on this, I'm pretty green when it comes to tuning. However I understand enough not to be dangerous. Recently I helped a friend tune his '88 5.0 to great success. He is now faster than a chipped 5spd c70 lol. In any case my tuning experience is limited to N/A cars. What are they general rules when tuning spark/timing for a FI (forced induction) car? in regards to a b5234t does anyone have a stock timing table? what rpm should I have max advance by?


I'm asking because I am considering MS-ing my '98 c70
