BTW, this is actually just as bad as turbo lag if not worse. When you spool a turbo, you're bringing it up to speed which is then compressing air and forcing it into the cylinders. With this, first you'll have the turbo lag as the exhaust builds pressure on the turbine side and then the compressor will have to pressurize the line coming back to the intake. Easiest way to explain this is putting your thumb over the end of a water faucet. Turn it on full bore and it's pretty hard right away to hold your thumb on there. Now take the same faucet and add 50 of garden hose to it and hold your thumb at the end of it. It takes a lot of time for it to pressurize to the point that it's hard to keep holding your thumb over it.

Also a little side note: 1/3-1/2 the pressure built in most turbos is from the high heat coming out and expanding. By the time it gets to a remote mount, the temp is a fraction of what it was at the manifold.

By no means take it as me raining on your parade but L.E.T. set about doing it this way right off the bat when they were working on a TT C32 but the turbos ended up back under the hood because the cons heavily outweigh the pros.

I'd save your tax money and invest it a savings account for the time being.
