However, it could be made better, gains could be made...theoretically.
That is quite interesting! Once again, I haven't gone into depth with this platform but typically a intake manifold is rarely restricting any gains. TB placement is huge though.

Regardless we should start at the basics fuel + air, from the start. Pump to injectors
Turbo Compressor Outlet - to intake manifold.

I don't foresee large gains in a intake manifold before any of that.
