Someone mentioned in a for sale thread that they have a Model S that has a software patch that disables the software nag for autopilot v1. I also heard a few years ago from someone with a P85 that had a software mod done that eeked out a little more performance. I'm not doubting that these were legit claims, I've just never heard of them before and I would think if you had a new software update come from Tesla it would overwrite these changes (or are they sticky?) Anyone know anything about these? Judgment aside please, I'd totally want the anti-nag message as it drives me batty and I seem to get it a lot on fairly uneventful highway drives.
