OEM ECM (ECU) upgrade for P+ 2015

So what do you think would happen if I just plugged the prestige ECM to my P+ Q7?

I wondered that same thing! Same motor and vehicle!
I know that GM uses the same chassis with the Buick, GMC and Chevrolet, same motors all different horse power, Buick being the highest. I believe they just flashed the ecu to make that comparable.

If your wanting to get S-Line 3.0 Supercharged power output, I believe there are hardware differences on the supercharger setup.. Why not just aftermarket tune it and upgrade the pulley?

I wanted to go as stock as possible... as far as I know there are no differences in hardware, but I'll dig deeper. I might just use that money to make it a better snow/mild off-road vehicle. I want to be like Dread!
