DME programmed?

I suspect this crazy power is coming from the tune. During the swap, of course, the engine harness plugs into the DME. It was in its stock location and appeared stock. If there were a chip, where would it be? I assumed it would piggyback on to the DME. Not seeing that only leaves a software change to the DME. Can a PIWIS show that? And, will PIWIS leave the program alone, or try to write the stock program over it? I wouldn't want that.

Surely someone here has flashed their DME and knows what "finger prints" are left behind. Thanks, Joe

I am not aware of anyone doing "piggy back" chip setups for these cars; most vendors reflash the DME. A PIWIS can detect a non factory flash, but will not overwrite it unless instructed to do so.
