You can help some on lower rpm by increasing timing, sure.
Next question - is this a PVL ignition system that does not retard, or a coil that retard as rpm increases? (makes a difference)
How much compression/quench are you trying to run, does your cam need a lot of ignition timing, fuel blend you are trying to run???
Then, forget your current gearing, because you have just moved the torque (and subsequently power) curves enough that your gearing will need to change with it.
If it's slow on the starts, it could be a myriad of other problems (clutch, cam, gearing, lean on bottom, exhaust, etc.) aside from the slow ignition timing. Yes, 30* sounds awfully slow for ignition on an open, that's more what a stocker runs. now, why was it set at 30* initially? Builder knew something that we all don't about your build?
