.022-.025" Basically as wide of a gap as you can get away with without misfires under high boost.

You want to run the largest gap you can get away without misfiring or blowout. You can run on the smaller end of the gap range and be a little safer, you will just go through plugs more often. By going on the larger end of the gap range you will benefit by also improving your mpg. My setup is way different than yours and running less boost but when I switched out to a cop kit I was able to increase my sparkplug gap to .031" with no issues and improve my mpg by 30 miles a tank.
With that said, try gapping at .024" and go from there.
