Enabling more power and/or efficiency is just a matter of swapping on a larger turbo, but why? I can't use any of that extra efficiency/overhead without going back into constantly-breaking-transmissions territory.
I don't care to total my car with a CD009 swap, and don't care to swap in a PPG gearset.
If I just want more power, there are other more powerful cars I can drive.
At the end of the day, I went turbo because I wanted to prove that a turbo setup can be done reliably. It just so happens a supercharger can put out just as much power at roughly half the cost.
Modern superchargers are far more efficient than I think you may give them credit for.

Really though, what turbo do you have on your car? It must be super small to have such a low max boost. It seems like such a small turbo would spool super fast like the A90 Supra's torque curve to 7 psi then plateau before seeing some boost creep as the engine muscled more boost out of the turbo up to 10 psi, but even then, the turbo would have to be a major restrictor and cause some back pressure. Are you just getting huge boost drop because of your giant FMIC? Or are you using a permanent restrictor plate or small bypass system to limit flow to the turbo?
I'm trying to wrap my head around how a small turbo could be so small as to max out on boost, but not choke the engine while naturally creating a ramp up without a boost controller. Are you using drive-by-wire to limit throttle input?
