Read http://www.sjmautotechnik.com/20vboost.html#level and you will see that 
removing ECU control authority over the wastegate (which is what you would be 
doing by disconnecting the WGFV as described below) might not make the 
"someone" very happy with their shiny new turbo at 1.4bar and no more.

"I'm sure this car would run much better without all these little hoses and 
wires all over in the engine compartment" ;)
