Anyone running larger spark plug gaps?

Anyone here running larger spark plug gaps? (1.0 mm - 1.1 mm)
I've seen posts saying that this increases performance, while others say, "don't do it, it makes the DI work harder". Dr Boost from SAAB HQ wrote that it DOES NOT make the DI work harder, he runs these gaps with no problem in a tweaked (high output) SAAB.
I came upon an interesting article which quotes NGK data--it looks like the DI ignition in SAABs, at 40,000 volts, should have no problem with 1.0 to 1.1 mm gaps. Click on the link below, scroll down a bit, and see the center graph on the bottom.
Not sure how increased turbo boost plays into this however. Maybe the upper left graph helps explain this? If so, it looks like even 2 bar of turbo should still not overwhelm 40 kilovolts of spark.
People also write that the copper plugs work better in DI cars than the platinum, because the platinum sometimes fools the DI into thinking that there's engine misfire when there really is none? Any truth to this?
Taliaferro's site says copper plugs are a must with a Speedparts ECU upgrade; I believe Dr Boost himself runs copper plugs.
