Plug gap for 3.3 NA2T recommendations

Hi, I haven't been on Z31P for a long time. The past five years I have neglected my fairlady so, I just spent around $4K having lots of needed work done including steering rack rebuild, Timing belt, water pump, rear diff mount, oil leaks, electrical etc.

I'm also doing a full tune-up and need some recommendations for setting the plug gap on NA2T 3.3L running 10 psi boost. I bought NGK blue plugs wires and copper plugs (BCPR6ES-11). In the past I have gapped them at the standard .44 but, I have read people running them as low as .28. I don't drive that hard and with my DXD stage three clutch nearing it's end of life I sure won't be doing any hard pulls.

I'd like to get some thoughts on where to set the plug gap as this is my daily driver. Thanks ahead of time.
