Thanks Sully,
I’m not sure if you are ‘talking your way out of this’ or not. As I see it, the car won’t be yours to decide what to do with, but will be owned by the leasing company or the company you work for.
If you decide to add a Tuning Box to this new vehicle, then it would be sensible to expect that that will adversely affect/invalidate the car’s warranty, and the bottom line could be that you will then be held responsible for any resultant issues not covered by that warranty. You will also need to inform whoever insures the vehicle.
A cynical old view, but if you want to arrive somewhere sooner for your business, then just leave a little earlier - sorry!
Kind regards,
Gareth.
