There is a lot of ECU upgrades like Hondata, Mugen, or Toda, and a few more I would think, so whats the best? Also whats the best to go with the Toda spec A camshafts, and uprated valve springs?

And part two best Intake Manifold Gasket? i think there is hondata's and ITR, maybe Toda has one but who's is the best?

Thanks for the help
