Explaining this to everyone else:
If you have a turbo-charger in an ICE, you can measure the PSI (ie, the air pressure) in the turbo-charger. This would typically be in the 10-20 PSI range.
Of course, the Tesla is not turbo-charged since it has an electric engine. The OP put SCUBA tanks in the frunk and put 3600 PSI in them with an air compressor, then made a joke that the Tesla had 3600 PSI as if turbo-charged.
