.030 seems good... but if misfiring is a prob then go down to .028...

But, I will be raising the boost to like 7 - 8 psi soon. And my timing is currently messed up, so I need to set it to something. What should I do for that setup?

if you're running 92 octane, stock timing should still be ok at that boost level...if you plan on upping the boost later, an MSD BTM or J&S might be a good idea...
