IIRC correctly timing is 12° maybe max up to 16°... but don't quote me on that. That was on my 93 Tbird with the 5.0 HO engine.

 

You can advance timing up to 14-16° as long as detonation isnt present and you're running high octane fuel.Make sure you remove the spout plug before adjusting timing.An open conical air filter can sometimes cause surging because of fan wash,especially if the maf sensor wasnt calibrated to that air filter setup.You can try doing the maintenance procedure to the 10 pin connectors too.They cause surging if the pinouts are loose or corroded.The second link explains how.
The first link is a surging idle checklist you can run through.
