OK. In 2000 (I think... old age... haha!) I had the "breaking up on boost" issue. Replaced wires and coils. A buddy of mine from the turbo import crowd said "plugs" and gap em for .035. This magic number has appeared in the turbo V8 crowd that I run with also. I have been running this plug gap ever since.

Over here, I see anywhere from .045 to .055 plug gap recommendations. My mod list is in my signature. What say you all?
