You can chip most turbo engines for higher boost which means higher HP and torque. Current 911 vs the 911S is 13PSI vs 16PSI on the exact same engine. If you want Sports Plus mode which adds a little more boost, more aggressive shifting, tighter suspension, and launch control its also just software changes that porsche bundles with a dash clock.
Companies have been doing this for awhile. Whats new is the subscription charge. Tesla has performance mode for $2k that you can buy and install over the air.
People will figure out how to hack these things. But the difference here, I think, is that EVs tend to be much more software-driven than even the most sophisticated ICE car. They're likely to contain half-decent crypto that makes hacking much more difficult, and EV companies are likely to sue you under the DMCA if you succeed. In addition these cars are always connected to the mother ship which can disable the engine by remote control if they suspect tampering.
"Chipping" an EV is going to be much harder than it was with ICE cars.
EVs only incidentally happen to seem harder to hack. ICE powertrains have more complex electronics and software.
This is also about ICEs having a legacy of repairability which makes modifications easier. Corporations being what they are, EVs are specifically made to be impossible to repair in independent shops.
