Default Spark plug tuning?-Big turbo

What plugs are you big turbo guys running on pump gas?
I'm running basically a 60-1@18+ psi on 93 octane, 850 cc injector w/ dual feed fuel rail setup. The problem is that I've been completely fouling my plugs on the street under normal driving(under 1k miles), I'm rarely in the throttle. I'm running NGK BKR7E's gapped at .032, I've tried BKR6E's but I've got to pull too much timing for them to run right. I know it's a rather fat map as far as the fuel tune is concerned, but it's nothing ridiculous.
Just curious to know what you guys are running or have had luck with. Open to suggestions.
Thanks,
-Adam

Sounds like you need to get a tune if you are fouling them. Another idea is to try Beru Spark Plugs. Harley Guys use these and they are supposedly foul proof, even running submersed in gasoline.

This is a WRX? That gap sounds a bit big.

What does nothing ridiculous mean? You have a wideband right?

BKR7E should work just fine at 0.028.
