I don't get what your really asking, but to have that setup managed by a missing link and an FMU would be absurd. This isn't 1998.

If your car is tuned, then you would naturally not be using a missing link. A missing link blocks the MAP sensor from seeing boost. Management systems are designed so the map sees boost, and therefore the system is reliably tuned (no need to go deeper, just trust me). FMU's once again, are not necessary when you have larger injectors and the management system tuned properly.

What's the issue your getting at? Your clearly aren't getting something...so what's the issue?

What are you using for engine management?
