I wouldn't do that.I'm just wanting to do something like unplug the EGR valve if it defaults to the closed position. I'm willing to put up with a Check Engine Light for now, until an engine tune is available.
I tried doing this with my TDI. Forced the valve closed with Ross Tech software. The ECU retarded the ignition timing and made it run like ****, lost about 10 MPGs.
You would need to re-map the fuel and boost to take advantage of the extra O2 in the clean airstream.
