On a different supercharged car I owned with MSD, I gapped the plugs to 0.025".

It ran a lot better than the gap MSD recommended for N/A cars.

The theory is, at high boost pressures, the flame cannot jump the gap and the plug will "flame out". This was so true on my other car when it would bang out at high RPM.
