Spark plug gap on turbo motor?

[66larkgs]

I am running .030 gap with 7 psi boost. Wanted to know what you guys are running for plug gap and should I tighten it up or open it up? I am running a 6 btm box with a steel headed Buick 401 nailhead with a t67 turbo.i have the timing locked in at 32* timing.

At that boost level 30 should be ok, but it wouldn't hurt to tighten it up a tad to around 26-28 or so to make sure it doesn't have a chance to "blow out" the flame.
