Assuming the engine is stock with stock compression, how much boost? I'd expect the short answer to be as much gap as possible up to the factory specification without running into boost induced "blow-out"
Longer answer: Once you're pressurizing the cylinder enough to induce ignition issues, gap down .002" at a time until it's tamed. All within reason assuming no other contributing factors like a weak ignition system, faulty parts, low voltage, oil/blowby buildup on plugs etc.
