It's obviously not a simple subject.

Looking at this link, they explicitly state the box does not increase pressure.

There's a lot of processing goes on in a tuning box. Hence the 'high' cost.

There's a lot it can't do, as you say, turbo pressure, torque limiters, top speed limiter....

But, I can understand that intercepting the pressure signal can have an effect on the injection time, if the signal feedback is not [just] changed in amplitude, but time displaced. Yes, it's fooling the ecu.

However, if it were just effectively reducing the signal, would it cost 300+.
Probably not.

Details on how it works seem a bit vague but, lets see what else turns up.....
