Spark plug gap is critical, for a few reasons. This usually shows up as stuttering and misfiring under boost. Not to preach, but it's the first place to look.
It's harder to make a spark as pressure increases, so it's harder to make a spark under boost. If the gap is bigger, it makes it that much harder for the spark to jump, so under high boost conditions, you get no spark. That's the misfire.
A second problem with large gap is that it can take out the DI cassette. If the spark doesn't jump across the plug gap, it's going to go somewhere. And that somewhere is internal to the DI coil. DI cassettes, fail for a bunch of reasons, but this one is preventable.
