I'd love to see some pressure gauge readings to support that claim. Getting different fluid pressures to the front and rear of a brake system would require a master cylinder with different diameter pistons operating the front and rear brakes. Getting different line pressures from a master cylinder with a single bore diameter would require repealing several laws of physics, with or without a power booster.
