Seems like this may only be true for 05 and newer models. Here's the response I got from ECUtek....
Most cars tuned can be put back to totally standard simply having an EcuTeK dealer putting a standard ROM into the ECU.
∑ This applies to all the MY04-on "Fly by Wire" generation which is most of the 2.5l models that ended in 2007.

However If your cars is a 2001 model year up to fly by wire that finished in 2004 (2ltr engines) then we wonít be able to reverse this unfortunately
