Elaborate on this for us. I'm curious. In particular about your own personal experiences with INTENSE and/or the Series 2 engine.

Buy the MPS system from the vendor you want to continue to do business with (for later replacement sizes).
Going to a 3.4 could cause you to need other mods. Just be aware of that. And it goes without saying that you should always run 91 octane minimum. More if you can get it when you start to pulley down or increase compression.
