probably not. Bernoulli's law.

p = .5 * rho * velocity^2

increase the pressure with factor x, the velocity increases with x^0.5.
Velocity * area = volume flow.
doubling the pressure will give 2^0.5 = 1.41 times as much fuel. Theoretically.

I dunno if efi injectors follow this rule exactly (because of the internal valve etc), but oil nozzles do.
