However, dynamic tuning, i.e., on a dynojet or whatever, is the best way to get the last few ponies out of your mods.

No question about this. Marc will add fuel so that you can take full advantage of the header swap, and the anti-backfire thing is an absolute MUST! Marc missed that in my initial tune (he fixed it for me immediately and at no charge, of course) and my Z backfired VIOLENTLY on every shift.
