Has anyone done this? If so, how much was the spend. I currently have the Insane Mode one, but want a little more "smiles connected to right foot".
it is $10K, plus installation and tax, I believe. I called the Miami-Dadeland store and they said they could do it to a Model X P90 (not the non-P, though), depending on its VIN. So, if you want to go for it, just call and give them your VIN to see if your car can be upgraded.
Thanks Domenick. I spoke to Davie store and they said that my vin does not qualify, which is just a shame. My production number is 20,9xx. So I am actually surprised that I cannot do anything to increase the speed
