IIRC, FCD is an outdated piece of electronics that isn't necessary with the proper support mods. I've read that it is still potentially damaging to your engine and therefore should not be used.

I'm pretty sure the lexus AFM, 550's, and upgraded fuel pump should allow you to safely boost to those pressures, but I would wait for someone else to confirm what I typed here

Yeah,

That can be a really smart upgrade to have when altering stock boost levels. To accompany it you will want an afr gauge though, this will tell you when you're running lean or rich... or hopefully Stoich! therefore telling you in which direction you need to adjust your afr regulator.

Again you'll also want the upgrades listed above. Those will allow 11-15 psi.

To make power you need more fuel and more air, your fuel controller will allow you to change the mixture to a certain but you'll need a wideband to see what your doing, or have it tuned

I have a wideband for 300 shipped
