Pump gas compression

Last fall Ford ran a new tv commercial for the Mustangs engine that did mention 10 to 1 compression. Seems the engineers finally figured it out. I have to think part of their success is in the onboard electronics making changes in tuning automaticly.
Then again they are building every day, every climate, every street, cars.
The hotrodder builds and tunes to suit himself. His price per gallon isn't even considered.
