For those of us who have N/A Limited coupes and like to look at that big "200" number, how hard would it be for us to put SRT-6 or AMG (provided the AMG physically fits or even shows 200) instrument cluster into our Limited cars? Would it sync right up? Would it be rejected by the ECU, anti-theft system, or other crazy electrical components of the car? Or would a chip tuning be necessary? What do you all think?
